2002 Ford ExplorerOkay, so, my back running lights for night will only come on when the lighting switch is turned to the auto position. However, when I have the switch in the auto position my dash back light will not work, that only works when the switch is in the on position. So, I really have an issue at night ha I can’t win either way! Advice on what the problem may be is really appreciated! I know enough to get by, but being a young female I still get some mechanics trying to rip me off. I would rather get someone else’s advice first!


RESPONSE

Sounds like you may have a relay sticking. Here is a copy of the wiring diagram to help assist in your troubleshooting.

2005 Ford FreestyleWe just replaced the serpentine belt on my 2005 Ford Freestyle and now the air conditioning won’t work and the belt is squeaky.
My car has an automatic transmission.


RESPONSE

You could try putting the old serpentine belt back on and see if it changes. The new belt may be the wrong size and slipping.

  1. Power steering pump pulley
  2. Serpentine Belt
  3. A/C clutch pulley
  4. Crankshaft pulley
  5. Serpentine belt tensioner pulley
  6. Alternator pulley

This vehicle is equipped with:

  • a V-ribbed serpentine accessory drive belt.
  • an automatic drive belt tensioner.

New drive belts should be of the same type as originally installed.

Drive belt chirp is a regularly occurring chirping noise that occurs due to:

  • pulley misalignment.
  • excessive pulley runout.
  • worn out belt.
  • incorrect tension.

It can be a result of a damaged pulley or an incorrectly installed pulley that was not correctly aligned.

To correct drive belt chirp:

  • determine the area from where the noise comes.
  • check each of the pulleys in that area with a straightedge to the crankshaft pulley for front accessory drive.
  • look for the accessory pulley to be out of position in the fore/aft direction or at an angle to the straightedge.
  • inspect the drive belt.
  • inspect the belt tensioner.

Drive belt squeal is an intermittent noise that occurs when the drive belt slips on a pulley during certain conditions such as:

  • engine start-up.
  • rapid engine acceleration.
  • A/C clutch engagement.

2003 Ford WindstarI just replaced blown head gasket on 3.8 engine. It ran rough and then smoothed out and ran. I looked under and noticed that the front exhaust was bright red. I shut it off immediately. Any answers how to fix this prob?


RESPONSE

Your fuel is probably to rich, and continues to burn during exhaust. Get it fixed as soon as you can. If there is a check engine light on, pull the codes and post them below in the comments. Did you double check your work to make sure you didn’t leave anything unplugged?

  • When this happens it typically means you have a clogged exhaust system, and it can’t escape. Can you feel any air coming out of the tailpipe at all?
  • Can be caused by the engine timing advanced too far.
  • Others say this is from the engine running lean. May be a sensor issue restricting fuel delivery.

1997 Ford Expeditionmy car is stuck in drive and won’t shift


RESPONSE

Are you saying the shifter will not move? Or the transmission will not change from drive?

This could be a couple of possible problems, the shifter is broke, the shifter cable is bad, or the trans has a problem keeping the shifter from moving. The easiest way to test it would be to remove the shifter cable from the trans and see if the shifter will then move, if it does you would know the problem is in the trans. If it does not move the shifter would need to be taken apart to see if a problem could be identified.

1997 Ford F350My vehicle will not charge. I have changed the batteries and alternator. I pulled the ground lines and cleaned them along with the positive cables. When the alternator is on the vehicle it checks bad and is not charging. When it is off the vehicle it checks good. I was told the voltage regulator was bad so I changed it and still not charging. I did get a reading with a volt meter that showed I had a good reading when one wire was on the positive cable and the other was on the wires from the alternator the case, the bracket but when I put it on the block I got a reading of not ground.??????can you advise what I should do next its driving me crazy as I am not a very good mechanic.


RESPONSE

Sounds like a wiring issue. You may have a bad ground or a shorted wire. Or maybe a bad inline fusible link. The bad fusible link is the most common cause. Isolate the wire and check for continuity on either side to see if it is bad. Unless you have a 215 amp alternator then the “Fuse Link J” is replaced with a large 300 amp fuse. Use the wiring diagram to assist in checking your charging system.

1986 Ford F-350Can’t get power past fuel pump relay?


RESPONSE

Looking at the wiring diagram for the Fuel Pump Relay. Black wire should be grounded. The Red/Yellow wire should be battery positive when activated and will connect power from the Yellow wire and flow through the Pink/Black wire to feed the fuel pump. If you are not seeing battery positive on the yellow wire, check the Inertia Switch.

fuel pump relay wiring fiagram 1986 Ford F-350

Two electric pumps are used on fuel injected models; a low pressure boost pump mounted in the fuel tank and a high pressure pump mounted on the vehicle frame. Some models equipped with the 8-460 (7.5L) carbureted engines use a single low pressure pump mounted in the fuel tank.

On injected models the low pressure pump is used to provide pressurized fuel to the inlet of the high pressure pump and helps prevent noise and heating problems. The externally mounted high pressure pump is capable of supplying 15.9 gallons of fuel an hour. System pressure is controlled by a pressure regulator mounted on the engine.

With internal fuel tank mounted pumps tank removal is required when servicing the pump. Frame mounted models can be accessed from under the vehicle. Prior to servicing release system pressure (see Fuel Supply Manifold details). Disconnect the negative battery cable prior to pump removal.

2003 Ford WindstarEngine lopes and rpm drops down to 3-400, warning lights sometimes flash. If I turn off A/C the engine will go to approx. 700 rpm and run fine.
As soon as I turn on A/C, it does it again. Runs great on highway.


RESPONSE

I see a couple of different possibilities why the AC Lowers Engine RPM.

  1. Could be an engine misfire. This means the engine isn’t running quite right on all cylinders. And when the added stress of running the Air Conditioning comes into play it causes the engines rpms to drop. This would also explain the check engine light flashing. Have the check engine light trouble codes pulled and post the codes below for further information.
  2. The Air Conditioning system have been overcharged and the engine is having trouble turning the compressor.

1990 Ford RangerWhere is the oil pressure switch, I cannot find it on my 1990 Ford Ranger 2.9L engine?


RESPONSE

NOTE: Oil pressure senders are used for oil pressure gauges, whereas the oil pressure switches are used for vehicles equipped only with a low oil pressure warning lamp.

The oil pressure senders/switches are located as follows:

  • 2.3L engine — left, rear side of the engine, in the cylinder head
  • 2.9L and 4.0L engines — front left side of the engine, below the cylinder head in the engine block

Oil Pressure Switch Testing

1990 Ford Ranger oil pressure switch location diagram

  1. To test the oil pressure switch, open the hood and locate the switch.
  2. Disconnect the wire from the switch. Attach one end of a jumper wire to the terminal on the end of the wire, then touch the other end of the jumper wire to a good engine ground (any bare metal engine surface). Have an assistant observe the instrument gauge cluster while you do this and tell you if the low oil warning lamp illuminates or not; the low oil warning lamp should illuminate.
    1. If the lamp does not illuminate, skip to Step 3.
    2. If the lamp does illuminate, replace the switch with a new one.
  3. Before jumping to any bad conclusions, try a different area for grounding the jumper wire on the engine. If the lamp still does not illuminate, touch the jumper wire end to the negative (-) battery post.
    1. If the lamp illuminates, the problem lies with the engine not being properly grounded.
    2. If the lamp does not illuminate, skip to Step 4.
  4. Connect the original wire to the oil pressure switch. While sitting in the vehicle, turn the ignition switch to the  ON position without actually starting the engine. Observe the other lights on the instrument cluster.
    1. If all of the other lights illuminate when turning the ignition switch  ON, the oil pressure switch is defective and must be replaced.
    2. If none of the other lights illuminate, there is a problem with power supply to the instrument cluster and gauges.

Oil Pressure Switch Removal

1.Disconnect the negative battery cable.
2.Disconnect the wiring at the sender/switch.
3.Remove the oil pressure sender/switch from the engine.
To install:

4.Coat the threads with electrically conductive sealer and thread the unit into place. Tighten the sender/switch to 10–18 ft. lbs. (13–24 Nm).
5.Attach the wiring to the sender/switch and connect the negative battery cable.
