So this is weird and hard to explain, but ill do my best. If i have the AC cranked, its not a problem, but this morning was chilly up in these parts, so the heater was on. Even on a low fan setting, there was a loud fan noise, but seemed to be coming from the back somewhere. Its like a high pitch fan noise, and gets worse the more you turn up the fan speed. Only with the heat, not with the ac.
is this normal? had to turn up the radio farily loud to drown it out...
thanks!
