Yeah, but it might sound a little tedious. I pal around in a 92 full size. Now, what you're gonna have to do is...
Remove panaling. After that, tear away any plastic that is there, make sure you save it. Tear it down till it's just bear metal.
Check the wires running from the motor to the switches, check for tears/frays. Check electrical connection to the motor and switch sets. Might be hard to do, so grab a flashlight.
If the motor really
is dead, and not an electrical problem, find all of the connection peices to the motor. They should be rivets. Pretty much impossible to remove without a dremel/drill.
Drill out the rivets.
Remove the motor, make sure you've taped up your window with something
stronger than five pieces of ductape. Trust me on that. Damn near broke the window. There should be enough wiggle space to take out the motor with out any cutting of the sheet metal.
Find a junkyard, and a blazer, proceed to tear through ever blazer looking for the left hand or right hand motor that you need. If you see dremel markings around where the rivets are, you're in luck, it's a replaced motor. Take a pair of abby's with you and CUT THE SHEET METAL surrounding the rivets. It's a whole hell of a lot easier than chipping with a sledge and screw driver. If you can't find one, you gotta order it. Hit the auto shop or dealership.
Now, you've got the motor, make sure you've got the mountings clean and accessible. When I put my motor back in, I said screw the rivets, and bought a set of something like 1/3 inch nuts and bolts, that I put in and then tightened and cut the ends off.
Make sure when you pop it in, that everything is connected. It takes a while, so set aside a weekend for this.
It's pretty much intuitive, just take your time, and don't get frustrated. Common sense my friend. If you need any help, I can take some photo's and maybe help you out.
