I have a weird problem. Sometimes my pwer locks work,sometimes they dont. I checked the fuses and they are good. I bought this car 1 year ago. The rear right door wouldn't lock or open when I used either the remote or the manual lock in the car.
Fine, I could live with that. Now sometimes only the front passenger will lock and the rest will not open or lock. So I close or open them manually and walk away. When I come back it opens fine with the remote and closes fine for a while. I can not discern a pattern but when the locks dont want to respond you can see them move a bit like they want to but they don't. THe manual to my car say that wires may wear but where do I check for such wires? I opened the door panels and checked those but they seem fine. Some advice would really be appreciated.

 

I had a similar issue in my integra, It ended up being the connection to the door from the car. The plug came a TAD bit loose, causing it to work sometimes, and not at others.
