96 SS no windows work

hello looking for some help on this randomly the other day the windows stopped working on my 96 ss i happened to have a couple spare parts to try on it but nothing seems to work .
changed out switch panel with known good one and still nothing switched up breakers in fuse box and still nothing. so i pulled off panel and chacked for power and low and behold THERES POWER at the plug but when i plug connector back into motor and measure then i get NO voltage?? what gives?
so i went and bought a new window motor plugged it in before installing and nothing it wont work. so i tried the motor on a battery outside of car and it works both ways? is this a lack of ground? or a short?

im stumped on this one guys any help would be great.

Check all grounds. Your ground is behind the A pillar kick panel on the driver's side. All of the window motors use that same ground.

1991 OCC 461 (.030 over 454) BBC, 3.23 posi, flash to pass, drop spindles & springs, Impala rims, Hydroboost, Recaros, MOMO/wood SW w/QR, custom wood shift knob, Pioneer DEH P77DH
1992 OCC now with 5.7 tbi, DEH P77DH

so basically where you rest your foot at on the rug at the bottom of the pillar? i will check those it has to be something like that cause all the windows were working, has to be a ground just dont see why theres no power when i connect the motor and power when i disconnect.

Make sure the wiring, and connectors have continuity.

ok i will try doing that. i noticed 2 things besides the windows not working. the dash illumination lamps donot come on and door chime not working.

i also noticed that with key forward if i go to put up or down the windows at the switch the ABS light on cluster comes on as i push switch????
then if i hold switch down all the way the ABS light will stop illuminating and the air bag light stays lit while still holding the window switch down?

why would it do this, last thing i though is that the abs airbags and windows were all working on same circuit. what can this be?


also checked grounds and all were nice and tight at that location.

When you have a lot of things acting stupid, it is usually a ground. This is especially true when lights come on when you do something else.


My brother had a strange ground fault on a 73 Fury...when he tried to start the car, the starter would click, and the headlights would come on dim. It turned out to be the main engine ground that was a through bolt to the water jacket...real smart engineers put electrical wiring in contact with water, with other metals in the system.

Sure sounds like bad grounds to me too. Had similar issue under the hood with a broken ground there causing other circuits to act weird.

Besides just Checking the grounds behind the kick panel, I would remove the screw and clean the connections to bare metal and reattach with some dielectric grease. They just use a sheet metal scre there into a drilled hole and the years of vibration and corrosion can cause them to fail.

If it were me, I'd probably pull both kick panels and do the same on the passenger side where you will find other interior circuits grounded there. Take it a step further if you want and clean up all the grounds under the hood too. If you look at my twilight sentinel install thread you will see pics of the grounds attached behind the passenger side kick panel. Just 4 or 5 screws and the entire panel lifts right off.
