Hello fellow Challenger lovers! I have a 1971 RT with manual windows. The driver side window keep hanging up and will not roll up. I have greased the rails and tightened the units inside. Anyone know steps to be taken to rebuild the mechanisms or otherwise solve this problem?
I had the same issue with my '71 Challenger and ended up replacing the regulator. I bought a new remanufactured one instead of risking a user rusty one off ebay. It all works great now.
