Why my power door locks on my 1988 GMC Sierra dont work

The truck was side swipe on the passenger side some years ago when my granddad had it. He had the passenger door replaced with a salvaged door and had the whole truck painted. I justed recently acquired the truck from him and the power door locks dont work. i replaced the switch on the passenger side and they still dont work. The power windows work though on both sides.

SOURCE: HAVE A 03 GMC SIERRA

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.

2008 GMC Sierra 1500.The only door lock that unlocks is the driver's door. Using either the fob or driver's side or passengers side lock buttons. Just the driver's side will open or lock.

test for power and ground at the non-working actuators. If they're getting power and ground when you activate the door locks, the actuators are bad. Keep in mind that they all work the same number of cycles, so it's no unusual for multiple actuators to fail at the same time.

My 2003 gmc Sierra driver side door panel quit working, locks quit, seat heater quit, windows quit, passenger side works fine

The most likely culprit is your driver's door control module... it's built into the driver's window switches. Double-check all your fuses before replacing any parts.

2003 GMC Sierra - intermittent behaviour on driver side power window. Passenger side and door locks work fine. Likely in the DDM module or motor itself ? Have disconnected and reconnected the connector...

I suggest replacing the switch on the passenger side. Chances are the switch is faulty by a back connection inside - switch is wore out - if it works every now and then.

Let me know if you need further assistance.
