On my 2003 gmc passenger power door nothing works. can

Power windows don't use fuse's , has circuit breakers
• PWR WDO CB 25A (fuse block) (System power for left and right windows 2-door vehicles. System power for LF and LR windows 4-door vehicles)
• PWR WDO CB 25A (IP wiring harness junction block) (System power for RF and RR windows 4-door vehicles)

Door Lock System Components
The power door lock system consists of the following components:
• The driver door module (DDM)
• The passenger door module (PDM)
• The body control module (BCM)
• The driver information center (DIC)
• The rear door lock switch
• The door lock relay
• The door unlock relay
• The liftgate lock relay--utility vehicles with liftgate only
• The reversible door lock actuators in each of the doors and liftgate
• LOCKS 20A fuse (rear lock/unlock relay supply voltage)
• ECC 10A fuse (liftgate lock relay supply voltage)

it sounds like a broken wire in the passenger door.

check fuses and relays if there good then there is a short in wiring open door and check wires make sure that they aint pinched or any broken wires on side of door between the fender should be a big harness with a rubber insulation.

If your power mirrors w not fold and the keyless entry is inop, it is the passenger door power controle module. ( the assy. with all the switches on it on the passenger door)

Take it apart again you probably didn't lock connectors tight or pinched a wire or something silly.
Go at it again slowly you'll find it.

if your main switch panel still works the passenger window and if door locks still work probaly bad window motor

There is a screw behind the lock rod. Lift door panel straight up to remove

yes it does sound like that is your problem. try checking for used one.

Check the 10 amp pdm fuse in the cabin fuse panel.

I had the same problem in my wife's 2003 Yukon Denali. The power seats and passengers side window wouldn't work. Turned out to be a blown Buss Type fuse in the Underhood Fuse Block. It is the one marked MBEC 1 50amp. Hard to tell if the are blown so look very carefully. Should look like a hoop with two shiny solderlooking bubbles on either side. On my blown fuse, it caught my attention because it looked like the solder was missing and I had to look very closely to see the bottom of the "hoop" was open. They are very hard to remove and must be pulled straight up.
This type of fuse looks like a red square with a clear plastic top showing the fuse link under the plastic. On my vehicle it is on the top row second one from the left.
