2003 Chevy Silverado Passenger door electrics and keyless e

The passenger door locks and window controls in my Silverado have stopped operating. At the same time, my keyless entry stopped working. I would have thought this coincidental, but have found similar complaints online. I have tried checking for a blown fuse, but cannot determine which fuse/ relay might be at fault. I cannot decipher the acronyms on the diagrams.[After a few more days, and exhausting all possible fuses, I've also discovered that the interior light no longer responds to the door (nor do the lights on the door light up when opened), the "passeneger door ajar" alarm on the dash does not respond to an open door - essentially it's as if the car forgot the passenger door ever existed. I'm lost ]

[quote="bluelightnin6"]Have you done or had any repairs made to vehicle recently?

Try spraying some WD-40 on the door ajar switch for that door. Sounds like it is faulty. Post results and I will follow up.

Thanks for using 2CarPros. Com![No repairs - left for the holidays and came back to the problem. Maybe it was like that a couple days before I left but I never noticed. I don't enter from the passengers side too often. The WD-40 does not appear to have changed anything. Is it possible that a connection has dislodged or a short is causing this. Seems electronic, - everything that is wrong is connected to that door in some way. ]

I have had the same problem and have tried everything u have said. Is there anything else to try?
