Window regulator replacement

Hi and thanks for using 2CarPros.com. There are two different sets of directions. One is for power windows and the other for manual. I am not sure which you have but the directions are primarily the same. As far as your question, I have always found it easiest to have the window in the up position when I start this type of job. When it is down, it is nearly impossible to access anything in the door because the window blocks everything.

Here are general directions for removal of the door panel:

No problem, Tom. I just hope it helps. And as far as the truck's age, I still say they built them better back then. Too much to go wrong with the new ones. Lol

Take care,
Joe
