Hi, bought a 93 J30 with 162k on it and who ever owned it just beat the hell out of it, the only window that actually goes up and down is the Passenger Rear window all the others the motors makes noise but the windows just rattle. Im trying to figure out what the process is to fix this issue seeing as how the Motors work but I figured the regulators (from reading on this sight), are bad. What I'm trying to figure our is how do I replace the window regulators, if anyone's had this experience hit me up.

There is a how to here http://www.fuzzycats.com/j30_diy.htm
