69 firebird. One slow window, one that opens with the drivers switch but not passenger switch and one back window that does not open or close at all. Thanks

You really need a wiring diagram. The key is that all the connections are made through the master switch, so windows can work from the master switch but it can still be bad.
Basically, the switches reverse polarity to the motor depending on the direction to run. The master switch feeds power and ground to the respective window switches when in the neutral position, then the window switch feeds the motor. The master switch feeds power and ground through the window switches (to the motors) when they're (the window switches) in the neutral position. You probably need to check voltage to the motors with a voltmeter.

On a side note, when I converted my 69 vert to power windows, I ran a ground wire (about 12-14 guage) directly attached to each motor to the inside of each door, making sure it was attached to clean metal. Windows go up and down way faster than my 2008 Impala. You must make sure your doors are good grounds. ( No paint between the door columns and hinges)

Not meaning to argue either, but I really have no idea how well or poorly the windows would've worked without the ground wire because I pulled the power window system from a 69 GP (never saw it operational before it was pulled). But I'm not sure I understand your statement about being grounded thru the wiring and not the motor housing. If I recall correctly, there were only two wires going to each motor which leads me to believe they are indeed grounded thru the housing. Anybody here know for sure?

Darn sure the ones in my 67 operate thru grounding of the frame. In fact, that how I tested them on the bench before putting them in. One lead for up, the other for down.

Charles, you're right (I didn't know) -- '67 motors had two windings, and applied power to one lead or the other to reverse. I don't know about a '69, but it'd be easy to test. Ground the housing and apply power to each lead and see what happens. It won't hurt anything if the windings are insulated from ground.
I can't find a '69 wiring diagram.

'72 is the same way. It grounds through the motor body and regulator housing. Previous owner didn't understand that and started tearing it all apart on my A-body. I checked with a meter and found the wiring is fine, the motor was bad (goes down but not up). +12V on one terminal and it goes up, +12V on the other terminal and it goes down - but regulator or motor must have a separate ground (or be bolted to the door and chassis ground system) to operate at all.

Personally I'd ground the motor to the inside of the car and not the door. Just run the ground wire thru the boot to inside and ground.

grounding power window motors
Now that you mention it, I believe this is what I did (Been a while). The rear motors I just ran a ground to the inside quarter structure underneath the interior upholstered panel. But with the doors why would it matter as long as you have continuity between the doors and the columns?

True, BUT, with the amount of current flowing there, it would be better without the hinge pivots in the path. |

I took mine apart and polished the armature and worked much better.
