Question about 2003 GMC Sierra 2500HD
My 2003 2500 Diesel has just developed a new problem.
The right window won't operate from the right or left doors.
The heated seat controls will not operate either.
The right mirror won't adjust.
The right door won't lock or unlock using the electric buttons although all the others do.
Also the door remotes won't work either.
The electric passager seat does work.
Everthing except the door lock remotes are in the passager door!
I thought about looking at the door harness but that doesn't explain the remotes not working!
I tried disconneting the batteries with no success.
Trying not to get ripped off paying someone to ''experiment'' at on my nickel!
Thanks for any help that comes my way!
Not sure if you have looked, but under the driver's side dash, is another fuse panel that houses the fuses for the right door. Might be a good place to start.

Tips for a great answer:
Passenger door module (PDM)
Body control module (BCM)
LR power window switch
RR power window switch
Window up and window down relays in each of the rear passenger window switches
Window lockout switch
Reversible power window motors in each of the doors (circuit breaker protected)
LT DOOR CB 25A (System power for left rear window)
RT DOOR CB 25A (System power for right rear window)
The power window system will operate anytime the retained accessory power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The DDM contains 4 power window switches which are integral components. Closing any of the normally open, rocker type switches provides the DDM with a request for power window operation. The switches for the 2 front windows have 3 positions Up, Down and Express Down, while the switches for the rear windows have only 2 positions, Up and Down. Each of these switches and their positions is a direct input into the DDM. Upon receiving a request for power window operation, the DDM, transmits a class 2 message indicating the switch and it's changed position.
The PDM contains a single power window switch that is an integral component. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation. The switch for the front passenger window has 2 positions Up and Down. Each of these switch positions is a direct input to the PDM.
The 2 rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows. However the BCM, upon receiving a class 2 message from the DDM, can control the set of relays which will activate the rear window motors.
