C3 window switch failing?

[enkeivette]

What is the usual cause of these window switches failing? The switch itself or the harness?

Over the decades I have seen the plugs corrode and get hot/burn up on the switch terminals, taking the switch with it.....now I also have seen the switches themselves fail.....but if you are careful, you can take the switches apart and clean/polish the contacts, and be fine.....do same with the pegs obviously....and work around/scrub the plug on the switch.....

NOW, years ago, there was a olde tyme TV tuner cleaner, for the contacts on the old mechanical tuners, it was called BLUE STUFF, I still have a can from 35 years ago or so, and use it sparingly.....it's a true miracle worker as my '72 vette and my 70 goat never had any window switch problems after being reworked with that shit.....

been a while.....:gurney:

I use Sonex spray, it cleans the contacts.

It was grounding out on the driveshaft tunnel. Surprised this hasnt happened to anyone else. Just glued some polyester under it.

If you want to improve the electrics, use relays 2 on each door. The loss through those switches is quite a bit. Windows fly up and down when using relays and a large 12V feed to them.
