93 Camry - Front Window Rolling Down

[gubber]

My front passenger window keeps rolling down. I think I need to replace the the window regulator and motor assembly. I found an assembly for 78.95$ on ezbodyparts.com. My questions -

1) How do I take the door panels out. Anybody have instructions? I searched the forums and found some posts, but nothing for a 93 camry.

2) How many screws and knobs are there to remove and what are the locations.

3) How difficult is it to replace this assembly?

Any help will be appreciated.

Thanks in advance
