POWER WINDOW CONNECTION

After a complete restoration of my 86 that included new doors, the power window switch on the drivers side became intermittent. I replaced the switch, used a bit of dielectric grease in the pin holes and carefully made the connection and reinstalled the blue plastic "hat" on the long pin. Still intermittent. If I push in on the switch body while activating the switch it works every time. Is the solution to squeeze the male and female connectors harder? It does seem they go all the way in. The switch works every time when it is not in the door holder. As soon as I reassemble the door card, problem arises. Afraid someday it will be stuck down and a storm will come up. Suggestions for a sure connection?

If it's an OE switch, it's old and worn out. If it's a new aftermarket switch, then it will work just like an OE switch that's old and worn out!

In other words....The OE switch is good until it's not good any longer. And the aftermarket switch sucks ass from day one. I'm sick of this crap and the same shit happens to me every time I mess with changing them out. Now, when I roll my drivers side window up, the passenger side goes down on it's own! Unless of course, I double hand the switch and push on the front finish plate while activating the button.

Dude! Good luck. I'll be watching this thread and rooting for ya!

Which window has the trouble from the drivers side switch?

Could easily be the factory wiring connector has an internal wire that needs to be squeezed a bit to make a good connection internally. In that case it will never work right no matter how many good or bad switches are installed.

Neither window works from the drivers side switch unless I push on it. They both work when I push on the switch. The passenger side switch works fine.

Then pull out the switches and you will find a plastic holder thingie that holds the wire . Open that up and squeeze the wire terminals so that they make a better connection on the posts of the switch. That should cure your problem.

I'll give it a try. Thanks.

There's no power to the switch(s) with the Ign Key OFF.

Pink is +12, black is ground, either one could be the connection problem.

All the other wires can be hot or ground depending upon up or down operation and shouldn't be your issue here.

It’s amazing how a 25 minute job becomes three hours!!

I separated the switch from the harness and found that to “pinch” the connectors tighter you have to remove the cardboard backing from the connector. Easy enough. Sure enough, the black ground connector had spread apart and was probably the problem. Pinched all the wire connectors and then proceeded to put it all back together. Two problems, due to the twisting of the wires, they want to leave their little slots and the cardboard connector refused to re connect on the three little nibs that were supposed to do that job. So in desperation, I widened the three holes in the cardboard so they would fit easily over the nibs, used gorilla glue to hold the wires in their little slots, and then used gorilla glue to re-attach the cardboard. Seems like a lot of work but it did seem to work. If the problem recurs, I think I’ll go for an OEM harness. I did take the opportunity to finally get door strap bolts one size larger so they won’t keep coming loose. Thanks again.

So the repair seems to be working but I suspect it will act up again. I've been checking the internet and keep coming up with GM Part number 12101916. Some websites say "this doe not fit your 1986 regal" but the picture of the connector looks spot on. I suspect it is not a full harness as the price ranges from $25 to $40. It might be that generic grey wires are connected and you have to splice in the correct color wires from the old harness. Anyone have any definite info on this?
