Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
2008 Chevy Uplander started to experience problems with the passenger sliding door. It would get to just about the closed state and open back up. The the alarm beeping began. The beeping continued even while the van was parked and off. Came out over 2 hours later, still beeping.
Sometimes the door would close and latch, but you could here the motor trying to open the door back up. And then the beeping, even while driving it would beep. Finally, I unplugged the two wiring harnesses from the motor for the sliding door and the beeping stopped, but so did the door motor. It does not come on at all now. Please help.
Start by reconnecting the wiring to the Power sliding door. Remove the PSD-15 amp fuse for 30 seconds. Reinstall the fuse, then follow the steps below to reinitialize the door module.
Also try cleaning the contacts at the leading edge of the power sliding door and the door jamb. You can use a Scotch-brite pad or steel wool.
Let me know if this works for you or if you need further assistance.
