Power window problem
The driver side window is in the open position. When I move the switch, nothing happens in the 'up' position. But when I move it to the down position, there is a slight click inside the door. The left window works ok.
Is this likely a switch problem? Is there any way to check?
BTW, this is on a 78.
Thanks!!

My brother had this exact same problem yesterday on his 81, it was corrosion in the connector for the window motor, might wanna start there and if its ok, work your way back.

Re: Power window problem (TFeld78)
Appears you have power to the switch. Could be the wires to the motor are bad - like broken off. That is what I had. So, need to take the sides of the console off and see if the harness in intack - no loose wires. If you have a test light and know how to use it, test power to the switch and then power to each other wire - the up (brown wire?) and the blue wire (down wire?). If not, problem is there. If so, then test, with the test light the wiring harness - grounding the test light to the motor. Test up and down. If OK, then problem is motor. Your are working out from the power to the switch to the motor itself. Hopes this layman's answer helps. BTW, just had to do same this past weekend. Turned out to be a bad harness at the switch AND a bad motor - both at the same time.

Re: Power window problem (Larry82)
Larry82,
I am a little bit of a novice on the electical part. The harness connection to the switch appears to be tight.
I have not taken the panel off the door yet, so I do not know the condition of the wires to the motor or the motor itself.
Can you give a brief explanation on how to use the test light, i.e. touching one probe to what and the other to what, etc.
Thanks!!
Tom

Re: Power window problem (TFeld78)
My drivers switch was intermittent so I removed the switch and sprayed electrical contact cleaner in through the top of the switch. When I turned the switch upside down a bunch of sand and dirt poured out. I used half a can of cleaner to wash the switch out. When it was clean I had half a beach (the car was in Florida for a while) on a paper towel. I tested for continuity between the contacts with the switch moved to both positions and everything checks out. :cheers:

Re: Power window problem (72GACRZR)
Thanks for the responses. Turns out the connectors at the motor plug in were dirty and a little corroded. After a little clean up work, I'm back in business!
Thanks 72GACRZR for the electrical lesson. I'll file it away for future use (I'm sure it will happen sooner or later!!)

Just did the same thing this weekend, same fix except that I had to tap the motor slightly with a hammer the get it working again, works fine now.
