Help Diagnosing Fan / Blower Issue
The fan/blower on my '89 stopped working yesterday. In my case, it DOES work when the A/C is on, but not at all when the heater or fresh air is on at ANY speed. It occured suddenly. There was a little ongoing chirping/squeaking (at low fan speed) before this happened, but nothing extreme. There was also a smokey odor when it happened. I have read multiple posts, but see nothing that replicates my exact problem. Most have the fan working only at high speed and the A/C not working at all. The closest I have come is a bad transistor, but I'm not sure this is the fix. I'm guessing it's not the blower motor since the A/C still works. Any ideas? Thanks, Greg
