Trunk Button Inside Does not work

[JasonBarrett]

For some reason my automatic trunk switch button does not work now. I have to use the remote on the key chain. When I press the button in the car it does nothing.

Any ideas?

Funny, This just happened to me this morning. I plan on checking it out this weekend. I let you know what I find.

I'm not sure what year LS either of you have, but for 2002, the same solenoid and relay is used for the remote and the cabin switch. The switch is simply in parallel with the keyless remote relay. When you press the switch, the orange wire and the violet/yellow wires are shorted together at the switch which passes current from the 25 amp fuse around the relay and to the solenoid. Check the switch for continuity, or remove the switch and short the two switch wires together. If shorting the wires causes the trunk to release, the switch is bad or was not fully plugged in. If shorting the wires does not cause the trunk to release, then start following wires!

Good luck!

Mine is an 01. Thank you for the reply, I bet this will be a pain in the butt to trace since there is not much room to start following cables.

Thanks, I appreciate it. I look forward to what you can find out.

Jason,
I checked it out, and it was the switch.
Part Number: 769216 >PA66-GF30<

I'll hunt around monday for a replacement.

Thank you for the information!

Well now I have a problem with the trunk release not working.

Tried the shorting of the switch wires. Nothing.
Checked the fuse in the trunk. Good.
And I applied 12v direct to the trunk release and it worked.
Is there a relay somewhere?

Did you look for the valet switch (reference post #3 above) and verify that it is not active?

By all means, try shorod's suggestion. Even if the switch is set to unlocked, try flipping it back and forth a few times to clean the contacts.

To answer your question. Yes, there is a relay somewhere. It's inside the REM (Rear Electronics Module). The REM is behind the trim on the right hand side of the trunk.
