Heater Blower not working


Asked by Jan 11, 2016 at 05:21 PM about the 1999 Ford F-250 Super Duty

Question type: Maintenance & Repair

The A/C,Heater blower in my 1999 F-250 Super Duty stopped working , I put in a new relay , and  changed all three control switches, ( fan, thermostate, and vent controls) . Double checked fuses, all good. Blower motor will work when we run a jumper wire from battery directly to Blower motor prongs.(To test)

Have you checked the resistor block? HTH. -Jim

Yes, The resistor on blower motor was the first item changed, coils looked rusty from moister. thought that was the problem, but still no blower, so we changed the control switches , but still nothing . Prior to trouble, Everything worked perfect , then blower motor would shut off after running a few minutes, then go on on its own while driving, then go off again. this went on for a couple weeks . Now I only feel heat coming thru vents, but no fan or blower.
