1997 Ford EscortI have a 1997 ford escort and was hearing a noise that the mechanic said was the spring or bearings inside one of the pulleys. I’m not sure which was the issue, the spring or bearings.  So I replaced the whole setup pulleys and tensioner. Before I could get to the carport I smelled hot melting rubber. After letting it cool down I could see smoke coming from the belt and it was hot. After getting it put back together, I started it and sounded good for couple minutes then the belt broke. Any idea what made it hot and break the belt?


RESPONSE

Most likely reason would be a locked up pulley or accessory. The accessories being the power steering pump, air conditioning compressor or alternator. The Air conditioning compressor or alternator would be the most common. With the belt broke already I would check these accessories before installing a new serpentine belt.

Try to spin them by hand. If they are locked up, the issue is found. Some of the pulleys may sounds off if an internal bearing is going out. These may need to be replaced but unless really worn out would not cause the belt to break. Only a locked up pulley or accessory would cause the belt to break. What happens when the belt slides over the locked up accessory component, it creates friction/heat and burns the belt in two.

  • Rotate the (B) drive belt tensioner in a clockwise motion to release belt tension.
  • Remove the drive belt from the accessory drive belt routing pulley (6C348) and slip it off the remaining accessory pulleys.

Installation

  1. Position the drive belt over the accessory pulleys. Raise and support the vehicle, if necessary.
    • Use a (A) ratchet or breaker bar inserted in the square hole in the drive belt tensioner flange.
    • Rotate the (B) drive belt tensioner in a clockwise motion.
  2. Slip the drive belt under the accessory drive belt routing pulley and release the tool. Remove the tool from the drive belt tensioner.
  3. Ensure that the (A) drive belt V-grooves are correctly seated in the (B) accessory pulley V-grooves.

2005 Ford EscapeGetting no fire to the spark plugs. I have changed two coil packs and spark plugs along with the crankshaft position sensor. What else could cause this issue?


RESPONSE

  • PCM Fuse
  • PCM
  • Ignition Transformer Capacitor
  • Wiring Harness
  • Camshaft Position Sensor

Engine Ignition – No Fire

The electronic ignition (EI) system is a coil-on-plug ignition system. The coil-on-plug ignition system consists of the following components:

  • Coil-on-plugs
  • Spark plugs
  • Crankshaft position (CKP) sensor
  • Camshaft position (CMP) sensor

The coil-on-plugs:

  • change low voltage signals from the powertrain control module (PCM) to high voltage pulses.
  • supply the high voltage pulses to the spark plugs.
  • are connected directly to each spark plug.

The spark plugs:

  • change high voltage pulses into a spark which ignites the fuel and air mixture.

The CKP sensor:

  • is a variable reluctance sensor.
  • is triggered by a 36-minus-1 tooth trigger wheel mounted on the crankshaft.
  • provides base timing and crankshaft speed (rpm) to the PCM.

The CMP sensor:

  • is a variable reluctance sensor.
  • provides camshaft rotational location information to the PCM.

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

1999-ford-explorer-wiper-washer-front-wiper-washer-circuit-1-of-1

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.

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.
