Question about 2004 Ford F150
If the system is a Manual ( not the EATC / Electronic Automatice Temperature Control System ) it is most likely the blower motor resistor.
For the new body style 2004 ( not the 2004 Heritage or Lightning models ), it is behind the glove box.
Open teh glove box, press on one side, to allow the glove box to hang down.
The Blower motor resistor is located in the side of the blower motor housing.
If your 2004 is a Heritage or Lightning, the blower motor resistor is access from under the dash / glove box arthe heating and air conditioning fan only works on - 7e8c043.jpgmg src="/uploads/images/7e8c043.jpg" alt="7e8c043.jpg" class="h_mi" />
On this type ( same as the 97-03 ) the blower motor resistothe heating and air conditioning fan only works on - 452e89b.jpgsistor and pigtail might need to be replaced.
Just pay attention to which body style 2004 you have ( new like the 2005-2008 or the 2004 Heritage / Lightning, which looks like the 97-03 MY trucks.
