Can't get my heater to work on my 156
I have a 1993 Chevy lumina van that has heat but doesn't have a fan how do I fix the fan?
A broken fan heater can not work and A FORD Foucs does not run
not likely as the heater fan only controls the air in the cabin, maybe the radiator fan has gone out too?

There are a couple of reasons why a heater fan isn't working in a 1007 Malibu. The fuse may be blown for the fan or the fan motor may need to be replaced.
