OK, bought the new window switch for drivers side, popped it in and ...nothing. What is the sequence for troubleshooting here???

Are you sure Nothing Happens? I had what I thought was a Nothing Happens problem with the pass. side window a while back. Tore apart the whole door to get at the switch and motor for troubleshooting (yes I'm a bit crazy) to discover that the window just needed to be oiled, because it was stuck in it's track. Oops. So just to make sure the problem isn't electical, does the window move at all?

Nope. Dead as a door nail. No noise, no movement, no nothing. Passenger side works great, so i assume its not the fuse. I would imagine checking to see if the wire has a current would be next, but i am not an electrical savant and hoped their would be an easier solution/diagnostic.

When I installed new window switches on my pcar, I installed the passenger side switch upside down. Easy as hell to do since it was not at all obvious which way was "up". So after days of frustration, I took it to my wrench and he tried "raising" the window and lo and behold, it lowered perfectly. He said it is an extremely common mistake. So I actually asked him not to fix it. I thought it was a pretty funny reminder of my amateur wrenching skills. So to this day it still works backwards. Gives me a little giggle every time I use it.

That's cute, Janus. Like that story. When my window was "dead" it didn't make any noise or anything either. (shrug) Yeah, next step is to start looking for voltages. If you know as much about that switch as I do (read:nothing) you'll end up spending a couple of hours pulling on the switch and reading resistances, then looking for voltages in the door. Eventually you'll pull the whole door apart to get at the motor and discover that you're not getting voltage to the motor, no matter what you do with the switch. Or that you _are_ getting voltage to the motor, and Nothing Happens there.

Anybody else have a better idea? Electrical troubleshooting is just such a hassle sometimes...

I had a problem with the passenger door control not working with a new switch. It turns out the bad switch was on the driver side which routes power to the passenger control. Your situation is different so I don't know if replacing all three switches will help. Sometimes the problem switch is not the one you are working on.

Checking your fuses wouldn't be a bad idea, just in case both doors are not on the same one.

Also, I remember from my 77 that, aside from the final connections right at the switch, there is another set of connections within the door. I had a wire disconnect there once, rendering the window inoperative until I reconnected it.
