Question about 2003 Chevrolet Silverado 1500
The passenger side door or window will not work . both are power . maybe coincedence but at the same time keyless entry quit working and the radio used to stay on after the truck was switched off for a certain amount of time or until a door was opened . now it cuts off immediately with the keyswitch. any info on which fuse or relay or what to look for would be greatly appreciated .. thanks in advance
I just went thru this with the drivers door. Windows wouldnt work, power mirrors, locks no matter if i used the key fob or the door switch. The inside light wouldnt come on when i opened the door. I did alot of research and found alot of people where having this problem but on the passenger side. I figured it was the door module but spent 50 bucks at the dealer to make sure. The dealer wanted some thing like 300 or so for the part. No junk yardaround Ct had any thing for an 03 chevy silverado. I found the part for 114 on oem, there are also place's like parts train and so on. That price included shipping to my house. Popped the ****** in and all my problems where solved. The part is called a door module, door switchs or maybe re something or other. good luck

Tips for a great answer:
The driver door module (DDM)
The passenger door module (PDM)
The rear door module (RDM)
The LH front power door lock switch
The RH front power door lock switch
The LH front door lock actuator
The RH front door lock actuator
The LH rear door lock actuator
The RH rear door lock actuator
The remote control door lock receiver (RCDLR)
The power door serial data circuit
The class 2 serial data circuit
The DRVMDL Fuse - 10 amp
The PDM Fuse - 10 amp
The RRINMDL Fuse - 10 a
Class 2 and Power Door Serial Data Links
The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible.
Your best bet is to take it to the dealer or an ASE certified repair shop .

Before you replace anything, inspect the connector pins in both the driver's door switch and the passenger door switch. If you don't find any problem with these connector pins, replace the driver's door control switch.
