I screwed up and pasted from Word again. Sorry.
I posted soemthing previously about this problem but have more information after this weekend. Maybe someone can help now.
I have a 1996 Civic EX Coupe. The power door locks stopped working on both doors. All fuses are good. I first tested the switch and have voltage there. I then removed the driver’s side door panel and disconnected the plug from the door lock control module for a few seconds and reconnected it. The doors then started locking and unlocking for a day and stopped again. I disconnected the plug again and it worked for a short time and stopped again. I removed the circuit board from the blue door lock control module box and noticed a burnt spot on the board where one of the resistors connected and that resistor was burnt. I replaced the resistor and the door locks worked for about a day again and stopped. The new resistor doesn’t appear to be burnt.
I went to various junk yards and found a door lock module out of a 95. I know it’s not the same module but I plugged it in and it would lock/unlock only the driver’s door.
I’ve noticed that when locking and unlocking with the old module, as well as the module out of the 95 Civic, there is not just a single pop when the actuator locks and unlocks. When I click the switch to unlock I hear the first pop when it unlocks and then a few residual pops like the actuators inside both doors are still getting power. It’s much softer sounding on either the lock or unlock but still several short bursts come from the actuators in both doors (only the driver’s door with the 95 civic module). If you can picture the 1st CLICK when locking or unlocking the door and then a quick “thud” “thud” “thud” at the actuators after the 1st click.
After hooking the module up from the junk yard and hearing that same noise I am wondering if the real problem is the driver’s side door lock control module or someplace else.
Has anyone else ever heard this noise? Can other Civic owners lock and unlock their door and listen around the latch area where the door closes into the car body and tell me if there is a single click when it locks or possibly some other noises after the first click?
I really hate to put out the money for a new module if it’ll just get burnt out because of some other problem.
Thanks in advance for any help.
