c-4 (95) Wiring schematic
Hi,
I tried the search function but I'm not able to locate the information on wiring schematics I need. Specifically, I'm looking for one for the drivers door on a 95 coupe. A new switch didn't solve the door unlock function. It will lock/unlock both doors from pass side switch but only lock with the drivers side switch so the driver solenoid/motor appears to be fine. Are there some schematics downloaded here on the site? Or, does anyone have a link to one. Thank you!

It appears only the driver side door lock switch could
cause the problem you describe.
Is this a new problem or did you purchase the vehicle like this?
Use an ohm meter or voltmeter and verify the switch contacts are being made.
Does the PKE in passive mode lock and unlock the
drivers door?

Thank you for the schematic. Interesting the in/out, switch/motor connections are all through the module. I haven't seen the remote for several years. It worked sporadically, as I recall. When the new door lock switch didn't work, I swapped it in for the pass side switch, worked fine. Pass switch installed on drvr. door, lock only. I'll pull the door panel this weekend & see what I can see. I'm afraid it probably is a module, though. Thanks, again.

This schematic shows the state of the switches inside the PKE module
and the ground path through the switches.
Still points to something with the driver side unlock portion of the switch.
Use a volt meter and while pressing the driver side unlock switch, measure the voltage on pin C the Light Blue wire circuit 244.
Compare the voltage when you press the unlock on the passenger side switch. They should be the same. Both switches receive 12 volts from the
Power Lock Fuse #42. A 20 amp fuse located in the passenger side end of dash fuse box.
and the ground path through the switches.
