Yeah. your BCM(body control module) has decided it doesn't want to work right. Since you can double click it and it works, leads to an internal problem with the BCM. Personally, I would live with it. New or rebuilt BCM's are cheap and then you have to have them programmed..$300+

SOURCE: power locks not working right

Hey, this might work.....get in truck, close doors, put key in ignition in lock position.....hold down the door lock button on driver side door control and wait for the lock control to be displayed on the information screen(odometer read-out).....it should say like lock 1, lock 2, lock 3, lock 4.....or something, I always reset mine to LOCK 1, to do this hold the odometer reset button on dash for a sec or two til it changes settings, then release, repeat till you get to LOCK 1, then quickly press and release odometer reset button to exit program, this is the function to lock doors over 15 mph and when out of park and to unlock doors when returned to park......yours' might be set to another function number....try it out, let me know if this helps.........good luck!

Hello
The power door locks and indeed most all power operated devices in the car are controlled by a central electronic module called the BCM (Body Control Module), the system is capable of "self testing" its functions and then it reports back to the scanner what problems were found with the systems it controls in the form of a body fault code, this test is run using a GM Tech II electronic scanner, you will need to have this test done to determine the reason for the lock problem. Once it is diagnosed to save money you can then do the repair your self unless the BCM is defective, in that case the new module must be programmed for your truck or the security system will not allow you to start the engine

SOURCE: Both Power Locks Lock But Wont Unlock. Remote will unlock the doors

If the remote key fob locks and unlocks the doors then the problem is more than likely the power lock switches, this is a common problem on the Venture Van.

I have a 2003 Hyundai Elantra. The remote locks the doors but sometimes it won't unlock the doors. I have to go to the passenger side, press lock on the remote, then press unlock (I can hear the 'clicks'...


Possible issue with the remote controller unit - main board or sub assemblies. The intermittent behavior seems to indicate that the board is erratic to detect at the same time the individual locks work at times.
So make sure all the connectors to the door and to the main board controller are tight. You can remove the main unit and check for any loose connections or clogging, specially water in all the door units or in main unit. If so dry and test.
Otherwise the main unit is a suspect.

2003 chevrolet tahoe right front door and window does not work


It almost sounds like the wire harness from the door to the body has become undone. There is a rubber tube you can see when you ope the door where the hinges are, in that tube is there the wires run through. Try playing with that and see if that will fix your problem. if not that's it's deeper in the body and most of the time it'sright behind the kicker panel by the corner there. Good luck

No power on front passenger door


Check the connections between the door and the body, not the panel on the door. If a wire was pinched between the door and body that could be the problem. There should be a boot between door and body, peal that back and look for damaged or grounded wires. Repair as necessary.
