2012 Ford F150My alarm goes off when I press the lock/unlock buttons on my fob. Sometimes the alarm goes off when unlocked or I can be walking up to the truck and it sets it off. Any advice would surely help. Thank you


The vehicle is not operating at all like the standard ford PATS system, the alarm (lights and horn) should only go off in the event the panic button is pressed. This vehicle does not have a perimeter theft system. It just has a coded key.

You need to disconnect the negative battery cable for 10 minutes. Then reconnect. Now lock unlock the door with the remote key fob then use the key and do the same, now try starting it. if this fails to work then someone has installed something else in the vehicle incorporated with the ford standard system or you have a faulty PCM.

Remote Keyless Entry (RKE) Lock/Unlock Control — Unlock

The RKE feature provides lock/unlock functions independently of key position, vehicle speed, or transmission position. The RKE feature provides a stepped (if enabled) process for unlocking the doors. Upon receipt of the first request for unlocking the doors, the RKE feature requests the BCM to unlock the driver door only and provides a long flash of the turn signals. If another unlock request is received within 3 seconds of the first, the RKE feature requests the BCM to unlock all the doors. This feature can be configured to global unlock, so that all the doors unlock on the first press of the UNLOCK button. Refer to Stepped Unlock Programming in this section for programming information.

Remote Keyless Entry (RKE) Lock/Unlock Control — Lock

The RKE feature requests that all the doors be locked when the LOCK button is pressed. On any press of the LOCK button with all doors closed, the BCM provides one flash of the turn signals. If any door is ajar, no flash occurs. As soon as the last door is closed, the BCM provides the flash of the turn signals. If 2 presses of the LOCK button are received within 3 seconds, the horn chirps once and the turn signals flash twice to indicate that all the doors are closed and locked. If any door is ajar when the second lock request is received within 3 seconds of the first, the RKE transmitter feature requests the BCM to chirp the horn twice without flashing the turn signals to indicate all the doors are locked but one or more doors are ajar. When the key is in the RUN or START position, the turn signal flashes and horn chirp confirmations do not occur.

Panic Alarm

The panic alarm feature provides audible and visual alarms which are evident from the exterior of the vehicle. The panic alarm feature requests that the turn signals are flashed and the horn sounds until deactivation. The flashing of the outputs occurs simultaneously. Activation of the panic alarm is accomplished by pressing the panic button on an RKE transmitter whenever the key is in the OFF position. At all other times this feature is disabled. Deactivation of an active panic alarm is accomplished by any of the following actions:

  • A second press of the RKE transmitter panic button
  • The key is switched out of the OFF position
  • A period of 2 minutes and 45 seconds has elapsed since the initial activation

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!


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.


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.

serpentine belt component location diagram 2005 Ford Freestyle

  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?


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


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.


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?


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.


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.
