Thanks to Gus, my problem has been resolved. I O U Gus.

 

I know you said that several things were done in parallel but what is your best guess of the cause(s) and solution(s) to the problem(s)?

Gonna make it up to the Cars and Pizza in Acworth next Saturday?

For the Atlanta area folks a few of us are going to meet in Acworth Saturday, the 31st for lunch. Love to have a big crowd, especially the active forum members within a day road trip of North Atlanta.

 

Gentlemen, your diagnosis and step by step as always is great. But if I may jump in, my concern is just the opposite. I replaced both rear window regulators and the top with rear windows worked the first few times, then failed. I had to wrench the latch open and struggle to get it to lock. It appears super stiff (as if the pressure has it locked). I press the switch to open and I hear the motor for two to three seconds and it stops. I heard something prior as to "unlocking the rams". Is this where I need to start? And if so, how would I do so? Your assistance is always appreciated.
