I do not mean to be hurtful and it will take some time to do. Maybe all day if you have no experience. If you need instructions just maybe you should have some do it for you.

2008 Cadillac CTS push button to open trunk sometimes works


Do you know anything about automotive electronic's ? The trunk release is controlled by electronic control modules . Having the vehicle check for DTC'S - diagnostic trouble code's should be the first step in the diagnostic procedure . Then reading how it work's !
Factory service repair info.
Rear Compartment Lid Release System Components
• Body control module (BCM)
• Remote control door lock receiver
• Interior rear compartment lid release switch
• Exterior rear compartment lid release switch
• Rear compartment lid release actuator
• Trunk release relay

Rear Compartment Lid Release Operation
The interior rear compartment lid release switch receives a signal from the driver door switch assembly (DDSA). When the interior rear compartment lid release switch is activated, the signal circuit is pulled to ground. The DDSA interprets this and sends a GMLAN serial data message to the body control module (BCM) requesting the rear compartment lid be released. The BCM responds by applying battery voltage to the trunk release relay control circuit which energizes the TRUNK RELES relay. The trunk release relay is supplied with battery voltage at all times. With the relay coil energized, the relay switch contacts close allowing battery voltage to flow to the rear compartment lid release actuator causing the rear compartment lid to release. The rear compartment lid release actuator is permanently grounded at G402.

The trunk release relay is located in the rear fuse box located under the back seat.

03 bonneville interior lights are staying on wont go off. what could be the problem?


The problem is caused by either a defective door ajar switch or the interior light relay. it can be any of the four switches, so the best thing to do is have the BCM scanned to see which switch is the issue. The switch is attached to the door latch inside the door.

Where is the interior light relay on 2001 ford windstar


Your interior lights are controlled by the GEM - generic electronic module !
Battery Saver The battery saver relay is controlled by the generic electronic module (GEM) and is located in the fuse junction panel. The battery saver relay is designed to supply B+ voltage to the following:
  • dome and map lamp switches
  • visor lamps
  • glove box lamp switch
  • interior lamp switch
  • interior courtesy lamp relay
  • delayed accessory relay
The function of the battery saver relay is to prevent excessive battery drain by interior lighting circuits. The GEM supplies a ground signal to the battery saver relay anytime one of the wake-up inputs of the GEM is activated to operate the battery saver relay. A wake-up command is sent when:
  • any door becomes ajar or is opened or closed.
  • the ignition key is inserted or removed.
  • the ignition switch is turned from OFF to RUN.
  • the ignition switch is turned from OFF to ACC.
  • a wake-up request is received from the remote anti-theft personality (RAP) module (if equipped).
  • The GEM will maintain the ground input with ignition in RUN or for 40 minutes from the last input activation with ignition in the OFF position. After 40 minutes the ground signal is discontinued.
This de-engergizes the battery saver relay preventing B+ voltage supply to the controlled switches and circuits.
  • Courtesy Lamp On Continuously
  • Short to power.
  • Damaged switch.
  • Generic electronic module.
  • GO to Pinpoint Test AF .
PINPOINT TEST AF: COURTESY LAMPS ON CONTINUOUSLY AF1 PRELIMINARY CHECKS
  • Check connections for clean tight fit.
  • Check for loose or damaged wires.
Do components and wiring check OK? Yes No GO to AF2 . SERVICE or REPLACE as required. GO to AF2 . AF2 CHECK CIRCUIT 53 (BK/LB)
  • Remove interior lamp relay.
  • Measure voltage at interior lamp relay connector Pin 87, Circuit 53 (BK/LB).
Is voltage greater than 0 volts? Yes No SERVICE Circuit 53 (BK/LB) for short to B+. RESTORE vehicle. RETEST system. GO to AF3 . AF3 CHECK CIRCUIT 434 (LB/BK)
  • Measure resistance between interior lamp relay connector Pin 85, Circuit 434 (LB/BK) and ground.
Is resistance 5 ohms or less? Yes No SERVICE Circuit 434 (LB/BK) for short to ground. RESTORE vehicle. RETEST system. REPLACE interior lamp relay. RESTORE vehicle. RETEST system. Interior lamp relay is located in the Instrument panel fuse box .

Wheres the liftgate switch located?


If your Nav is the same as my 03 windstar and I'm not sure it is, mine are located one on each side about 3/4 ways down inside the liftgate. I took the interior panel off and was able to locate them. I then cut the wires to the switches and tied the wires together to each switch. Of course this makes the car think the gate is closed all of the time. Even when its open. That was fine because i don't know about your Nav but my interior lights would not work nor the doors would not lock when you put ity in gear. My wife says is this safe to do? Like daa if you don't know that your liftgate is open and you need a idiot light to tell you that. come on. Good luck.

03 ford expedition interior lights stay on and door ajar reads


This is a very common problem with Fords. I have one that was doing this as well. What works for most people is pretty much what you have tried - spraying inside the latch all over with WD40 Until it's coming out the bottom of the door. If this fails to work, the switch probably needs replaced. The switch is located inside the door near the latch. It should be pretty easy to find once you have the door panel off. Look for the wires leading to it. A new switch is usually very inexpensive, but may have to be purchased through your local Ford dealer. If you're not comfortable taking the door panel off, a mechanic should be able to do this repair for you in less than an hour of shop time.

98 explorer fog light always on


reference your owners manual for relay location, if you do not have one you can download it at www.fleet.ford.com , the relay for the fog lights should be under hood in power distribution box, ford relay are notorious for hanging up in closed and open positions, pull the relay and see if the lights go out? if so replace relay, try the same for interior lights, that relay should be inside in the fuse box. hope this helps, let me know
