heater

On my 96 7.3 my heater dosent work all the time will work one day but say the next two it wont. When it dosent work u can still feel heat comin out of the vent but wont blow out even on high it still dosent blow. Any ideas. Live in iowa so its a pretty cold ride. Thanks alot to any ideas. Merry christmas to all ford enthusiasts!

It doesn't blow on any speed? I'd look at your fuses first. Someone may have tapped into one for some accessory and it's loose now. Something is loose somewhere.

Heater switch and the heater motor should be considered as suspect as well.

Sounds like an intermittent at one of the connectors.

Don't forget the fan resistor, too. They usually are the first item I check.
