Door lock trouble shooting/Keyless entry

hey yall,

so I am tired of manually unlocking doors. I have no idea on where to start to test why it is not working. when i press the switches on the door i hear no relay clicking in the box by the kick panel. but when I press the lock button on the remote i hear a click. when I press the unlock button on the remote it is silent. My trunk pop button does work perfectly. but that is the only thing that works on the system. from some wiring diagrams it seems that the trunk is not wired with the other locks (correct me if I'm wrong.)

You need to provide basic into, like the year of your car.

It is a 1995 Camaro Z. With I believe a 1996 pcm and engine. I have no idea how to check if that is true. The guy I bought it from said him and his dad blew the original engine to to reusing the bolts for the piston rod caps.

Shoebox has the 1995 wiring diagram:

Keyless Remote:

The hatch release switch bypasses the keyless entry receiver. The door lock buttons do not bypass the receiver.

I assume by "the box by the kick panel" you mean the keyless entry receiver in the passenger side kick panel:

Let me see if I can get the attention of our electrical guru.

Re: Door lock trouble shooting/Keyless entry

First, do you have a multimeter or some kind of continuity tester? That type will have a battery inside, not just a light. If not, get this one: 3 Piece Circuit Tester Set
If you buy this one, you will also need one AA battery for the continuity tester in the kit. Test the tester by touching the alligator clip to the pointed probe tip; the light should come on. If you don;t want to buy the kit, see the instructions below for bypassing the keyless entry module.

Unplug and remove the keyless entry receiver module behind the passenger side kick panel. Using the continuity tester, check for continuity between the following contacts in the black C2 socket (black) of the module (not cable): B (goes to red/black wire) to C (goes to gray wire), H (goes to one tan wire) to A (goes to orange/black wire), and H (goes to one tan wire) to G (goes to other tan wire). If all those check ok, the module is ok so reinstall it and plug in the cable. If not ok, you will have to replace it or bypass it. The continuity tester will light up when there is continuity. You may have to use a small piece of wire at the alligator clip end in order to make contact in the connector.

To bypass the keyless entry module temporarily: unplug it and jumper the following terminals in the black cable (not the module) connector C2: B to C, H to G, and H to A. For temporary use, ordinary straightened small paper clips may be used. Try to operate the door lock switches, if they work the module is defective. If they do not work, continue with checking the switches.

But first, report back here with your results.
