Dodges are good for blowing fuses. If that is not it, the fan switch might need replaced.
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!
There might be a bad fuse causing the heater to not work. Check the fuses if they are all ok you may have a bad blower motor. when you turn the heater on and no air is blowing then it is your blower motor.
check the relays.If it doesnt blow air at all then check the blower relay or fuse
If the heater does not work, check: -heater fuses and/or any heater relays -heater control head -heater blower motor resistor
blower motor bad or no power to it chech fuses blower switch blower motor
The problem exists somewhere in the circuit for the HVAC blower. Check fuses and relays. If they check out, check for power and ground at the weatherpack terminal which connects to the HVAC blower. If that checks out, then your blower motor is probably bad.
it in the fuse box in the drivers foot well on when you see two rows of fuses it is on the bottum row i think it is number 26 for the heater blower it in the fuse box in the drivers foot well on when you see two rows of fuses it is on the bottum row i think it is number 26 for the heater blower
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.
The blower motor resistor circuit board has gone bad. Replace the blower motor resistor. I did Still dont work Try the fuses...Had the same problem and it was a blown fuse.
There is an electrical short to ground in the fan switch or in the blower motor itself.
The heater blower motor is #19 in the power distribution box under the hood, which also houses your relays.
Check to see if you are getting power and ground to the blower motor - if so blower motor is bad. If no power possibly fan switch or selector switch Also check the blower motor resistor, found in heater plenum.
All fuses are located on the drivers side under the panel. If you cannot get your heater blower to come on, it could be the relay located on the blower motor on the passenger side under the dash. It's a little difficult to get to. Len
Those are two seperate circuits. Start with checking the fuses. There is a fuse for the radio and a fuse for the heater blower motor.
Check fuses Could be a defective ignition switch
where is heater blower relay for 1989 BMW 535I
if it doesnt work on 1 and 2 it could be a blower motor resistor but if it doesnt work at all check the fuses, relay and check voltage if it reads 12 v replace the motor
heater blowe motor relay is under the hood,behind the battery there is a box that has a round knob u unscrew and on the back side it tells wich ones are wich. there are also fuses for the blower motor.that is the problem i am having. everytime turn heater fan inside car on it blows afuse.not sure why.has new resistor.
Perhaps a bad fan motor? Perhaps a bad fan resistor? Perhaps a plugged evaporator coil?
check fuses,see if ones blown check power at blower, don't forget the fan switch ,there famous for going out.
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.

Beause there is probably a short/bad connection in the switch, or the blower motor itself
Check your fuses.
