There are two relays inside. Next 2 checks have to be done with each relay energized.

Energize the lock relay by connecting the A terminal to the positive battery terminal & the D terminal to the negative battery terminal.
Check for continuity between terminals C & B (I’m expecting your problem to be here or the 2nd check above)

Energize the unlock relay by connecting the F terminal to the positive battery terminal & the D terminal to the negative battery terminal.
Check for continuity between terminals C & E
I'll check that tomorrow before I go to work, thanks

Sorry Corey, I wasn't meaning to hijack your thread. I was posting my problem in here because I was thinking we may have the same basic problem. I did find mine to be the relay that Technical Ted described. Mine is under the drivers seat.
Part # VBA-2002, 12065122
Thanks Technical Ted for the help

BTW, I pulled my seat and then I pulled the carpet back to get to it.


Here are some pictures of my relay and what I found. Sorry the pictures didn't turn out that great.

I think mine may have gotten wet somehow. You can see a white film in the corner of the plastic shell. It'* also on the bottom of the circuit board.

that fuse was the problem for me (or at least I think it is). I'll be looking at a scrap yard soon to find a GM car with power locks soon
