I have a '95 Integra Sedan and my door lock system quit woking yesterday without any prior problems. The Haynes repair manual that I have said that it could be either fuses, switches, solenoids, actuators or the ECU. I have already checked the door lock fuse and it's ok. The solenoids in the doors don't seem to be making any noise when I try to unlock the doors on either of the front doors. If anyone has had a similar problem before, feel free to let me know or give me your ideas. I have a feeling that it has something to do with the ECU, but maybe not.

 

I had a similar problem in my 1998 GSR. About two months after I purchased it (used), the passenger side door lock started sticking with no prior problems and no incident. Raised havok with my keyless entry.

 

I do not have my Helms here at work but if there is nothing else wrong I would question it being the ECU. My guess is that it is a relay somewhere that died, but I can check the wiring diagram later when I get home.

 

If they stopped working altogether, the problem either lies with the No. 6 fuse in the underdash fuse box or with the power door lock control unit. Here is a troubleshooting chart and wiring diagram for the circuit:

 

Thanks to Schmoo I no longer need to consult my Helms and I echo his comments.
