So, my door locks work with the alarm remote. This tells me it isn't an actuator on any/all of the doors, since they WILL lock and unlock. However, none of the lock buttons inside the 1999 Suburban will work. The doors still lock and unlock when the ignition is turned on and off, but the buttons don't work at all. It means that I need to completely turn off the truck to get something out of any of the other doors. It's annoying. I thought I checked all the fuses, and I didn't see one that was bad. I went to a junkyard, and they were nice enough to let me try their switch before I paid for it. Nope, a different switch did nothing. Thoughts???
