door lock and trunk issue

slownlow43 · 04-02-2011, 11:00 AM

Ok guys, I'm asking for help again. Just picked up a 99 Alero to replace my 02 and the power door lock, remote trunk, and fog lights don't work. When you press the buttons manually or with the keyless remote you can hear clicking under the dash like its trying to perform its function. Has anyone else experienced this issue?

The only thing shared in common between these functions is that they're controlled by the BCM, but if the relays are clicking, then that's working.

Does it only not work right when you use the keyless entry?

Not to thread jack but I have the exact same problem. Only difference is my trunk will only work with my remote starter fob but nothing in the car will trigger it. I'm curious to hear any ideas.

i would get a multimeter and try to test the lines while you hit the buttons and see if/where there is a short/break in the lines for those solenoids.

It ended up being the relay for each of those functions. I wasn't aware they had their own relay before I posted this thread. Thanks for all the help.

Which relays are they and where are they located?

I believe all three were located in the drivers side interior fuse panel.
