Power Door Locks Circuit Description
The power door locks are operated by reversible motors. The motors are found in the following locations:
• In each front door
• The side door
• The rear door
The PWR ACCY circuit breaker (30A) supplies voltage to the door lock motors.
If you move either power door lock switch, mounted in the front doors, the LOCK applies voltage to cavity F of the door lock relay. This energizes the lock coil in the relay. Current then flows through CKT 295 (GRY) directly to the following components:
• Both front door lock motors
• The side door lock motor
• The rear door lock motor (cargo doors only)
CKT 246/294 (TAN) provides the ground for the motors. The normally closed contacts of the UNLOCK then contacts the door lock relay.
If you move one of the door lock switches to UNLOCK the polarity of the system reverses. Current flows through the energized UNLOCK relay contacts. The LOCK relay contacts provide ground.
When the UNLOCK button is pressed once on the RKE transmitter, only the driver door unlocks. If it is pressed a second time within 5 seconds, all doors unlock.
If the side door is open, the side door jamb switch ground signal is opened/broken. If you move the door lock switch to LOCK while the side door is open, the following actions occur:
• The 2 front doors lock
• The rear door locks (cargo doors only)
When you close the side door, the door jamb switch closes. This closes the ground signal to the body control module {CKT 775 (PNK)}. A 5 second timer then starts in the module. After 5 seconds, cavity A4 connector C1 of the body control module supplies voltage to the door lock relay via CKT 195 (LT BLU). This energizes the door lock relay, which sends voltage to the door lock motors in order to lock the side door. Refer to Door Jamb Switches, Liftgate Strut Switch for a schematic of all door jamb switch inputs.
If the side door opens during this 5 seconds, the 5 seconds timer is reset. The locking pulse takes place at the end of the 5 seconds. Unlocking the door resets the 5 second timer in the body control module.
Use the following components in order to unlock the door lock system:
• The LH power door lock switch
• The RH power door lock switch
On vehicles equipped with cargo doors, the cargo door opener mechanically opens the door once the door lock system is unlocked. On vehicle equipped with a liftgate, the liftgate lock/unlock release switch (mechanical key) is added in order to serve the same function as the front power door lock switches. These functions locking and unlocking all doors, including the liftgate. Once the door lock system is unlocked, press the liftgate release switch in order to electrically open the liftgate and pull the handle in order to open the secondary latch.
Could be the button switch on the drivers side door jamb, check see if it is stuck, if you have a door ajar light this won't come on with the door open either because the switch is pushed in, which is another indication it's not working. try pushing it in by hand and see if it does anything, It should push in and when released pop back out.
not real clear on what you mean. if your door is not closing try lifting up on it as you try. also lift the door handle and see if the latch mechanism is open.
if you mean that the doors are closed but the light won't go out then you need to replace the door jamb light switch, open each door one at a time and push the little button in the door jamb if the light goes out then you may just need to adjust the switch, close each door before checking the next, if you need to adjust it then here is a generic picture of an adjustable switch
if the light doesn't go out then you may need a new switch.
The obvious choice is the cheapest. Somewhere in the door jamb is a small push button switch which either closes opens a circuit when the door is closed. That state is relayed to the computer which turns the interior lights and the door ajar system on or off . The switch generally either screws or snaps in. So as a first step I would get another switch and replace it. If it still does not work then I think the fault lies in the computer, however it is a VW and I have been wrong before.
Check your push in button on door post or door jamb area. Use your finger or thumb & push it in, and lights should go out, as if door closed, let it out & if lights flicker, time for a new switch, or try spraying it good with contact cleaner may help.
The door latch has a switch built into it to replace the old door jamb switch. If the switch is faulty the system will think the door is ajar. A scanner will show an open switch.
One of your door jamb switches is broken. Look on the inside of each door jamb, you'll see either a plastic button that pushes in, or it may be covered by a rubber boot. Press each of them, and one of them may feel funny. If there's a rubber boot, pull firmly to remove it, then there should be a screw holding in the switch -- remove that and slide the switch out and unplug it. Should be very cheap (<$20) to get a new one from the dealer, and takes maybe 5-10 minutes to install.
