SOURCE: remove ignition switch

U must dis-arm the airbag 1st, disconnect the battery for 30 minutes before you begin work, then remove the airbag, the retaining screws are at the back of the steering wheel down in holes I believe, after that remove the safety clip at the top of the steering wheel threads, then the steering wheel nut, you will need a steering wheel puller to remove the steering wheel, they are about $10 from any parts store, after the wheel is removed remove the airbag clock-spring rotating contact, then remove the turn signal switch, there will be 3 screws holding the turn signal switch in, remove them, then remove the lower trim under the dash and crawl under and and disconnect the large flat connector at the bottom of column, this will allow u to pull the turn signal switch up and out of the way, don't force anything be patient, under the turn signal switch on the right of the area above the ignition lock cylinder u will see a black headed screw, it may be a tamper proof torx/star screw head or a phillips, remove it, then turn the ignition to the on position and slide the ignition switch out, reverse it all and put it back together. take your time, don't rush, good luck, contact me with any further questions.

SOURCE: 03 Chevy Suburban says right rear door ajar when closed

Replace the rear door pin-switch if needed after testing proper operation.
It is telling the alarm the door is open all the time.
Most likely corroded terminals or wire.

SOURCE: the automatic lock keeps locking and unlocking

If your vehicle is equipped with an aftermarket security system, it could be causing this. I have removed several these systems from my customer's cars for the same reason. GM has technical service bulletins that discuss this as well as other driveability/emissions problems that these systems have been causing.

If there is no aftermarket in your car, I would scan the Body Control Module (BCM) first to see if the computer knows anything.

No codes - I would look into a possible loose connection or bad switch in one of the door panels.

SOURCE: All of the door locks but one on our 1999 GMC

there is a relay but if it were bad none of your locks would work. your problem is the door lock motor it is a little electric motor that actuates the lock. its also called a door lock actuator. kind of expensive and a little difficult to replace.

2005 Chevy Impala. The door locks keep locking during drive.


It's probably a bad input to the BCM - body control module ! Have it checked for DTC'S - diagnostic trouble codes .
The automatic door lock function can only be enabled by the body control module (BCM) if the driver door open switch and door ajar switches are in the Closed state. For information on programming the automatic door locks, refer to Vehicle Personalization in Personalization.
DTC B3064 or B3069
DTC B3127
DTC B3128, B3133, or B3138
DTC B3132
DTC B3137
DTC B3272
Your best bet , take it to the chevy dealer . Unless you own a GM factory Tech 2 scan tool an have access to factory sevice repair info.
.
The outputs to the door lock actuators are controlled by the body control module (BCM). When the BCM receives a lock input from a door lock switch, or a keyless entry transmitter, it applies battery positive voltage to the door lock actuator lock control circuit, a ground to the door lock actuator unlock control, and the driver door lock actuator unlock control circuits. When the BCM receives an unlock input from a door lock switch, it applies battery positive voltage to the door lock actuator unlock control, the driver door lock actuator unlock control circuits, and a ground to the door lock actuator lock control circuit . When the BCM receives an single Unlock input from a keyless entry transmitter, it applies battery positive voltage to the driver door lock actuator unlock control circuit and a ground to the door lock actuator lock control circuit to unlock the driver door. A second Unlock input from the transmitter applies battery positive voltage to the door lock actuator unlock control circuit, and a ground to the door lock actuator lock control circuit to unlock the passenger doors.

This diagnostic procedure supports the following DTCs:
• DTC B3128 Left Front/Driver Door Unlock Circuit High
• DTC B3133 All Door Unlock Circuit High
• DTC B3138 All Door Lock Circuit High

2004 suburban doors randomly lock and unlock while driving


There are two relays that control the locks. One controls locking, the other unlocking. One of those could be defective. Replace one. If that corrects the problemyou are good to go. Do not discard the old relay yet. If the problem persists replace the other existing relay with the old on you just removed. I believe the lock relay actually works through the unlock relay or vice versa.

2002 Chevy 4wd


maby im wrong but if you rev up and only rear wheels spin that means that it might be 4 wheel drive but not constant 4 wheel drive or diff lock system ,,,, ,, in 4 wheel drive all wheells will turn together but if pressure of slip is bad enough or torque high enough only 2 wheels will drive ,,, thats why diff lock locks wheels together in each axle to over come this ,,, all wheel drive like in landrover locks all 4 wheels together to ensure all wheels rotate to give best grip

The Rear Wipers on my 2001 1500 Chevy Suburban Stopped working


Unplug the connector at the rear wiper motor, turn the switch on and probe the wires with a test lamp, if you have power back there you more than likely have a bad motor. If there is no power start checking fuses they are all labeled easily on the back side of the fuseblock covers both on the dash and underhood. Good Luck!!!

Need steps to reprogram chevy suburban 1997 keyless entery


1. Locate the Data Link Port. It is located under dash drivers side. Be sure you know
which pins are 8 and 4.


(Note port is wider at top) Your OBDII port will not

2. Make sure there are metal contact pins in terminals 8 and 4. Connect 8 to 4 with a
suitable jumper wire (leave the jumper wire connected throughout the programming
procedure). Make sure you know which terminals are 8 and 4. The vehicle will respond
by locking and unlocking the
doors to signify entering of programming mode.

3. Press and hold both the LOCK and UNLOCK buttons together on the first transmitter to
be programmed. After about 15 seconds, the vehicle will respond by locking and
unlocking the doors. Release the buttons on the transmitter.

4. Within one minute, repeat the previous step on the remaining transmitters to be
programmed.

5. Remove jumper wire applied to the OBDII Port.

1996 Chevy Suburban Electric Locks


It might be that driver side control unit. They've been reported to have problems with short circuits (even mine has had problems) Check fuses. However, a junkyard is probably the only hope for finding those relays -GM generally doesn't make them anymore.
