Can anyone tell me where to find a replacement rear back up camera for my 2007 Avalanche. Can't seem to figure this out. Does GM part# 15173619 work??

 

Free FIX I have had the same issue on a 2007 Chevy Avalanche. There is a wiring harness connector under the vehicle that goes to the tailgate. Mine was on the drivers side and close to the rear. I disconnected it and noticed corrosion on one of the pins. Sprayed PB Blaster in it, connected and disconnected it a few times to clean connectors and BAM!! Works great! Be careful when disconnecting, dirt and debris collects and will fall in your eyes!
