Heater Cores and Blower Fans
If the heater fan doesn't work and all fuses are good as is the blower motor relay what's the problem with the heater fan?
Motors do go bad. Directly wiring the fan to a 12 volt power
source will tell you if the motor is toast. If it won't work when
directly wired to a power source, look for another motor.

Why is my blower motor rear defroster and AC controls not working all of a sudden Not even the LED lights light up on a 1998 Cavalier Help The blower motor was starting to fail as I had to tap it .?
Ok..I figured it out. Turns out the rear defroster is the problem. When I unplugged it from the back windshield, blower/heater works great!! So...to all those out there..if your blower motor blows fuses...check the blower motor first...then the HVAC and heater fuses, then rear defroster if you have a cavalier!

Where is the 1997 Escort blower fuse?
Why does your heater not blow air at all?
First check the fuses (all of them). Next, try turning the fan to high (with the engine running) and gently tapping the heater blower with a hammer. It it blows, you need a new blower motor. Next connect a 12V test light to the two wires at the blower motor. If it lights up, the blower motor is bad. Otherwise you have en electrical problem.

Asked in Ford Explorer XLT
What fuse controls a heater on 98 explorer 4.0 v6 sohc?
The heat is provided by radiator coolant circulating through the heater core. This is a mechanical process and no fuses are involved. There are fuses for the control panel and the blower motor and the system will appear "dead" if the fuses are blown. If the problem is lack of heat or control over the temperature of the system, the problem is most likely a mechanical failure of the blend door. This door regulates how much air is diverted through the heater core, and is a common failure on the Explorer. HeaterTreater has developed an inexpensive fix for the problem.
