Taurus tempermental heater fan

Twice the heater fan in my 2003 Taurus SE, 36000k, stopped working. I tried every heat/ac/defrost setting to no avail. Both times about 30 minutes down the road the fan started blowing again and has worked fine since. Sounds like a drive you crazy problem since it is so sporadic. Any ideas? Big Walt

If the two speeds went out and now the upper three have failed, it is time for a new switch. The drop would probably be the compressor kicking in.

Thanks. I was able to rule out a blown fuse, so a quick fix is out of the question.

How difficult is it to install a new switch?

Is this something I can do or should I leave it to the pro's?

Personally I never take anything to the pro as you call it. There is a lot of satisfaction in repairing it yourself. But that depends on your level of comfort and tools. The center console needs to be attacked and you keep whittling away until you get to the switch.

Thanks for the donation!

Just so I understand, the intermittant problem is volume of air not loss of heat?

Is the production date between 5/1/01 and 12/15/03? The born on date is on a sticker in the door jamb. Oops that's bud, the production date :)

Yes, the fan is not running at all. You can feel heat if you put your hand near a heater duct. Production date is 09/02. Thanks

Ok, There is a Technical Service Bulletin (REf # 04-15-03) regarding water intrusion into the blower case and also in some cases onto the passenger floor. It involves installing a rain hat extension seal, replacing (likley) the blower motor, possibly the resistor and the cowl panel. Nce this blower case is accessed, there will likely be corrosion present. MAybe you can get in there and clean and seal connections and get lucky. Then install the rain hat.
