1999 Ford ExplorerI cant get my wipers to stop unless I pull the fuse. I replaced the multi switch and when I put the new one in, when put on high the washer fluid would start to spray. I put the old multi switch in another truck 1997 explorer it worked fine. Also changed the front plastic part of the motor (not exactly sure what it is called). Checked the wiring under dash and the wiring harness going to the motor. All working properly but there is a teal wire that I cant get any reading off of with my light tester. And the wire goes to the power distribution box with a BUNCH of other wires and cant sift through.


RESPONSE

Looking at the wiring diagram, I would lean toward a relay sticking and back feeding. Most likely the WIPER RUN RELAY.

Front Wipers /Washer Wiring Diagram 1999 Ford Explorer

Wipers and Washers—Front

The wiper system has four different operating modes: off mode, low speed mode, high speed mode, and interval mode.

In the off mode, there is no windshield wiper motor activity, and the windshield wiper motor is in the PARK position.

In the low speed mode, the windshield wiper motor is set to a low speed setting. The windshield wiper hi/lo relay is deactivated, while the windshield wiper run/park relay is activated.

In the high speed mode, the windshield wiper motor is set to a high speed setting. The windshield wiper hi/lo relay and the windshield wiper run/park relay are both activated.

In the interval mode, the windshield wiper motor is set to a low speed setting with the windshield wiper hi/lo relay deactivated. The windshield wiper run/park relay is activated at the beginning of each wipe and deactivated when the windshield wiper motor park switch reaches the RUN position.

The permanent magnet three-brush windshield wiper motor allows selection of either low or high speed, when selected the steering column mounted multi-function switch (13K359). When the multi-function switch is in the LOW position, the common brush and low speed brush are used. When the multi-function switch is in the HIGH position, current bypasses part of the armature winding to the high speed brush. When the multi-function switch is moved to the off position, the windshield wiper motor will continue to run at low speed until the windshield wipers (17500) park.

When the multi-function switch is in the interval (INT) position, the windshield wipers will make a single sweep followed by a pause. The control knob on the end of the multi-function switch adjusts the pause from approximately 1-20 seconds.

Vehicles equipped with a generic electronic module (GEM) are available with the speed-dependant interval wiper feature. During the interval mode, the delay between successive wipes will decrease with higher vehicle speed to compensate for increased water on the windshield glass. This feature will relieve the operator from constantly switching between interval settings.

 

Dwell Intervals for Each Switch State
Delay/Wash Switch State Dwell Interval
0-10 MPH 65 MPH and Above
1 (Long) 18 18
2 16 5
3 13 4
4 10 3
5 7 2
6 4 1
7 (Short) 1 0

 

If the washer switch is pressed between 100 ms and 300 ms, with the mode switch in the OFF position, the wiper system will provide one low speed wipe with no wash.

To engage the windshield washer, push the knob of the multi-function switch toward the steering column (3C529). When the multi-function switch is in the OFF or INT position, the windshield wipers will run as long as the knob is depressed up to 10 seconds. When the knob is released, the washer will stop immediately, but the windshield wipers will continue to run for two to three sweeps, then return to their previous set operation. Washer engagement does not affect windshield wiper operation when the multi-function switch is in the LOW or HIGH position, but the washer will be deactivated if the knob is held greater than 10 seconds.

Feature inputs:

  • Ignition switch RUN position: (battery potential on both RUN and RUN/ACC inputs).
  • Ignition switch ACC position: (battery potential on RUN/ACC input only).
  • Wiper switch position: (different resistance for each mode; see Wiper Switch Resistance Values table).
  • Interval Delay/Wash switch position: (different resistance for each mode; See Interval Delay/Wash Switch Resistance Values table).
  • Windshield wiper motor park switch: (ground for PARK position and battery potential for RUN position).

Feature outputs:

  • Windshield wiper hi/lo relay control: (ground to activate and open circuit to deactivate.)
  • Windshield wiper run/park relay control: (ground to activate and open circuit to deactivate.)
  • Washer pump relay control: (ground to activate and open circuit to deactivate.)

1995 Ford ContourDriving along the road the other day car just completely stops, power went out. I have battery but my car won’t start what may be wrong?


RESPONSE

If the engine does not crank – most likely reason would be the battery is weak from the alternator not charging it. The engine was running off the battery by itself because the alternator was not charging it. Now the battery is probably to weak to start the engine or keep it running. Check to make sure the alternator belt did not come off.

1994 Ford E-350Where is the fuel injection fuses located?


RESPONSE

The fuel injectors are operated by the PCM – Powertrain Control Module. This is the engines computer. The PCM has 2 main fuses and a PCM Power Relay. They are located in the engine compartment fuse panel. Fuse U and Fuse C, both 30 amp fuses.

Fuel Injector Pressure Test
  1. Connect pressure gauge T80L–9974–A, or equivalent, to the fuel pressure test fitting. Disconnect the coil connector from the coil. Disconnect the electrical lead from one injector and pressurize the fuel system. Disable the fuel pump by disconnecting the inertia switch or the fuel pump relay and observe the pressure gauge reading.
  2. Crank the engine for 2 seconds. Turn the ignition  OFF and wait 5 seconds, then observe the pressure drop. If the pressure drop is 2–16 psi (14–110 kPa), the injector is operating properly. Reconnect the injector, activate the fuel pump, then repeat the procedure for other injector.
  3. If the pressure drop is less than 2 psi (14 kPa) or more than 16 psi (110 kPa), switch the electrical connectors on injectors and repeat the test. If the pressure drop is still incorrect, replace the disconnected injector with one of the same color code, then reconnect both injectors properly and repeat the test.
  4. Disconnect and plug the vacuum hose at EGR valve. It may be necessary to disconnect the idle air control valve and use the throttle body stop screw to set the engine speed. Start and run the engine at 1,800 rpm (2,000 rpm on 1984 and later models). Disconnect the left injector electrical connector. Note the rpm after the engine stabilizes (around 1,200 rpm). Reconnect the injector and allow the engine to return to high idle.
  5. Perform the same procedure for the right injector. Note the difference between the rpm readings of the left and right injectors. If the difference is 100 rpm or less, check the oxygen sensor. If the difference is more than 100 rpm, replace both injectors.

2001 Ford ExpeditionMy 2001 Ford Expedition with 160,000 miles drives fine sometimes and then others it idles rough and sputters. It cut off in reverse yesterday and the mileage disappeared and then it cut off once while in park this morning. On the way home after 5 mins of driving it was fine but the mileage disappeared again. Codes are reading fuel injection, misfire and o2 sensor. I replaced the o2 sensor but the code is still coming up. Help please.


RESPONSE

Please take the time to post the codes below in the comments for further evaluation.

2000 Ford ExplorerI have a 2000 ford explorer XLT. I’ve been having issues where my remote does not unlock all of the doors, in fact the switches inside the vehicle sometimes doesn’t unlock all the doors. Sometimes the doors unlock but sometimes the drivers side front door and passenger side front door do not unlock. I replaced the door lock actuator in the drivers side door a few months ago b/c I thought it would fix the problem. I’m still having the issue. Also, the keypad which allows you to unlock the door seems to want to work (it makes a noise when i press the code) but it doesn’t unlock anything. Any thoughts?


RESPONSE

The good news is the door locks circuit isn’t to complicated. That means there isn’t to many things that you need to look at. I have attached the door locks wiring diagram below for visual reference. Looking at the diagram you can see there is only one fuse. You know the fuse is good or it wouldn’t work at all. Next you will see three relays. This is where I believe your problem is. When a relay starts to fail it will sometimes work and sometimes not. Same as what you are describing. Next would be the door switches and finally the door lock actuators. And of course the wiring harness in between.

Since your door locks seem to be able to lock just fine, I would start with the door unlock relay.

If you are trying to use a new or replacement remote you may need to program the remote.

Programming Remote 2000 Ford Explorer

NOTE: All keyless entry remote transmitters (15K601) are programmable and must be set at the same time.

NOTE: To program (or reprogram) the keyless entry remote transmitters into the RAP module, perform the following steps:

  1. Make sure that the anti-theft system is not armed or triggered.
  1. Turn the ignition switch (11572) from OFF to RUN eight times within ten seconds, ending in RUN. If the RAP module has successfully entered program mode, it will lock and then unlock all doors.
  1. Press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed.
  1. If the door locks do not respond for any keyless entry remote transmitter, wait several seconds and press the button again. If the door locks still fail to respond, refer to Diagnosis and Testing.
  1. Turn the ignition switch to the OFF position, or wait up to 20 seconds after step 2, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the RAP module will lock and unlock all doors one last time to confirm.

2006 Ford TaurusI have a 2006 Ford Taurus with P0300 Ford random misfire. changed: manifold gasket, fuel filter, spark plugs, wires and coil pack. the misfire is off and on and at idle.


RESPONSE

P0300 FORD – Random Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

The P0300 code means that a cylinder(s) is misfiring or is randomly misfiring. Start by checking for intake leaks, intake gaskets are common caused of multi-cylinder misfiring. If no leak are found the next step is to replace the spark plugs. If the problem persist more tests needs to be done to diagnose problem, see “Possible Causes” below.

Possible causes

– Faulty spark plug (s)
– Faulty ignition coil (s)
– Clogged or faulty fuel injector (s)
– Intake air leak
– Fuel injectors harness is open or shorted
– Fuel Injectors circuit poor electrical connection
– Ignition coils harness is open or shorted
– Ignition coils circuit poor electrical connection
– Insufficient cylinders compression
– Incorrect fuel pressure

– Sticking or faulty fuel injector
Possible symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
– Lack/loss of power
– Hard start
– Engine hesitation

head gasket 2005 Ford TaurusHow much would a mechanic charge to replace head gaskets on this car?


RESPONSE

Much would depend on the engine as it may be DOHC (Double Over Head Cam) or not.

Around $1600 this includes gaskets, coolant, oil, cleaner, misc and labor.

The gasket set is under $100 plus mechanic mark up on parts = $150 – $200

Looking for help troubleshooting problems
No acceleration on hills actually truck will slow when throttle is pressed. If gas petal is feathered truck will maintain speed eventually will slow down
Recently bought truck has new fuel pump, filter, catalytic convertor and O2 sensor. seem like the last owner was chasing some issue?
Truck will run great 70 mi. then act up is key is turned off truck will run fine for 4-5 mi then die. Leave it set and it will run great again
thanks


RESPONSE

Your in luck as it is a 1995 Model. This means you can pull the Computer codes without a scan tool.

Post any codes found below in the comments for further help. If no codes are present than I would be looking at fuel pressure drop on acceleration. A drop in fuel pressure may be from the a leak or a failing fuel pressure regulator. At idle fuel pressure should be around 30 psi and should increase to 35-45 on acceleration.

If the problem seems to happen more when the engine is hot versus cold, I would lean more toward the ignition control module as it is the most common failure component in the ignition system for this year. And there will be no code for this.
