Been there done that...start by removing the center console (pulling it back as far as wires will allow. Next, clear all wires and vacuum lines away from the white cylinder visible behind the fan/heater control panel. Take a 1 inch wood drill bit and drill a hole about 2 inches from the seam in the center of the cylinder on both sides of it. Take a flashlight and get a peek at the location of the bearings (where the shaft meets the motor). Get some good penetrating spray w/ straw and spray onto shaft at bearing, run the fan to work it in, then get some teflon spray or white lithium spray and repeat. When you're finished, cover the holes with duct tape. A piece of advice...speaking from experience I can tell you that this only works for so long. I did this every three to four months for about a year until eventually the fan raised the white flag and died. Replacing a fan isn't all that bad, especially on a 92 because I don't think you have to modify the housing...just plug and play, the job just takes a while and involves some extensive disassembling and cussing. Good luck.
