I just repalced my driverside regulator. I bought a new replacement regulator and motor combo from ebay for $58 shipped to my door. Everything came out real easy. I pushed the window all the way up and removed the assembly. Then I took the replacement regulator and used four nuts and bolts of the correct side and inserted them and snugged the nuts down while it was out of the vehicle. Then I took my cheap 110v mig welder on low and just tacked the nuts down to the back of the regulator. Then pulled the bolts out, inserted the regulator into the door, and bolted it in. Only took a sec to tack them in and I am sure it saved alot of time and cuss words.

Lubed everything up and it works good as new.
