Power locks don’t work and only one window works

[DontPressureMe]

88 chevy k2500

Just as the title says.
for awhile i had to lock the doors by hand , and i randomly sprayed WD-40 in the key holes cause it was hard to unlock

and out of random i decided to push the lock button on the passenger side and, the doors locked for the first time in years.
then they stopped later on

i swapped the button around and it was still the same outcome, nothing worked.

i got a test light, grounded it, and back probed all the buttons and wires
the lock button on the driver side never got power
the window button (only one that works) got power
the button controlling passenger window got power but didn’t roll down

passenger side power lock button got power
and the window button didn’t get power

i’m sure the door lock actuators work cause they locked for a little. as for the window i think it could be the motor but not sure so any help would be appreciated

A lot of times the wires break where they bend in the door jamb, and it's hidden by the boot. The insulation can look OK but the wire is broken inside, so check there.

Also the sticky door locks is almost always due to gummed up old lube in the slider plastics on the inner door panel (the metal panel screwed into the door skin, behind the interior trim panel.) Cleaning that and the rod of the old lube then applying some fresh white lithium grease can help a lot.

No. It's behind the interior trim panel, as I said. You have to remove the trim panel, and the rods slide through plastic clips that are attached to the inner door panel; the same sheetmetal piece that holds the window regulator.

Gonna take a little bit more work than just shooting WD on stuff.
