My front heater fan is not working - Cars & Trucks

What kind of vehicle is it. Could very well be the fan is wore out.

Check the fuses first. If they are good, then check the fan speed on lo, med, hi. Do any work (esp high?) if so it is the the resistor that is typically located in the front air plenum by the passenger foot area (4-5 leads). if not, it could be the blower motor itself - I have replaced one on a 1993 Honda Accord. Depending on model, this could be 30 minutes to 4 hours job. (I did mine in 2.5). Of course make sure connectors are solid under the dash in general...
