Check your electrical connections on the fan motor. They could be loose.
Run a new ignition switch controlled "hot" wire directly to fan motor
heater fan broken.
you need a new heater fan its burnt out
how can I cheek the heater fan on my 1990 geo metro to see if it is bad or if the switch is bad. I want come on at all when you turn the switch on check fuses and they are good.
fan motor could be bad
was there something on your dash that fell in the vent, a bad fan will make noise all the time.
Possibly the Heater Motor, if the fan is not coming on at all the bearing in the motor have probably gone out.
first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all. The first thing i would check is if the fan motor is blowing any air at all. If not u need to put in a new heater fan motor. first of all i hate to say an obvious answer but does the heater motor even turn. Does it blow air at all.

The heater may not be on - but the fan still blows air through the vents when they're open !
Remove the wiring harness from the back of your 1994 Chevy heater fan motor. Remove the heater fan motor retaining bolts. Remove the fan from the front of the heater motor. Reverse the process to install the new heater fan motor.
