the power windows on my car started going bad (moving very slowly) so I inquired about having the motors replaced, they quoted me over $400

WTF, fuck that shit! So I decided to to try and replace them myself. It turns out that the motors are wedged between fiber glass and if you don't have instructions on how to change them, it seems basically impossible, so most people that try, give up and have the dealership do it. Luckily I found a site on the net, someone had done it, took pictures, and made instructions. Bought both motors on ebay for $45 each, so it only cost me $90 and a couple of hours instead of $400 plus.
