2003 Silverado Passenger Door Module. It controls the door locks outside power mirrors and the power windows for the right side. I have a 2003 Chevy Silverado 2500HD 4X4 Duramax Crew Cab and my right side front door lost all the functions. Verified that power is getting to Driver Door Module. I removed the power window module from the passenger door and measured 12 volts was getting to the switch.
I ended up buying a new one. At The Same Time My Keyless Entry Stopped Working. Leave it disconnected for 5 minutes or so. Bought a replacement switch on ebay that was out of an 04 Silverado and had the exact same part number on the back. Interior light stays on. Remove the right front door panel and disconnect connectors from the Passenger Door Module switch.
Before nothing worked now the mirror locks and window work with the new one.
I can manually unlock the door. I had my right passenger door go dead a couple of weeks ago. Pull the door module backwards and upwards. I heard there is a DDM Driver Door Module that can go bad. Verified that power is getting to Driver Door Module. I was asking you earlier about the passenger door module on my 2003 silverado.
