Front Window Help

[madmax2b]

Need some help. The Passenger side front window (1970 Challenger with Power windows) falls towards the front of the car when rolled down. You push it towards the rear as you roll it up to get it to seal correctly. I have taken the door panel off and looked for anything that is obviously worn out, but nothing seems bad. Not a body guy, so would appreciate any advice any of you guys/gals might have.

Oem or after market regulators?

The Factory Service Manual has instructions and diagrams on winow adjustments. If you don't have one you can just download one from the Resources tab on this site. Pages 777 to 779 .

Sounds like something is badly worn, or broken

If you don't have a FSM yet, you can always remove the other door panel and compare to the side that works to see if something is damaged or broken.

Did the car come with them originally?
There is one guide support that is different from manual to power is why asking about originality.
Did it work and then did it start acting up? Or has it always been an issue?
Pictures always help if you can share them.

I have an original PW car along with one where I installed factory unit so I have a fair amount of knowledge on them.
