1994 Oldsmobile Ciera • 6 cylinder FWD Automatic • 205,230 miles

I recently purchased a '94 Olds Cutlass cutlass cierra sl and have been having problems with the h/ac fan. I have checked the motor, fuse and the fan multi-speed switch and they are good, so other than the wiring, what would cause the cabin fan to run intermittently or not at all most of the time? Is there a controller of some type hidden under the dash? Thanks!

Does it have auto temp control?
Have you determined whether it's power or ground that is dropping out at the motor?
