Sounds like you have a short somewhere. You'll problebly have to take it in to a mechanic to get it fixed. I know that's not much help but if you didn't know there was a short I'm sure your not going to be able to fix it either. Good luck.
You most likely will have a bad blower resister........
try wiggling the wires at the blower resistor if don't work then tap on blower motor
its the blower resistor.
Depends on what you mean by heater will not work. If the blower motor will not work, it can be a blown fuse, bad blower motor, bad blower motor switch, or a defective blower motor resistor pack. If you mean that the blower motor works but there is no heat, then it can be a clogged heater core, thermostat stuck open, or defective heater control valve.
from what i have read it is the blower motor resistor it goes bad and only lets the fan run on high google blower motor resistor and read on
Most likely a failed blower resistor.
blower motor resistor is burned out
try replacing the blower motor resistor
The blower motor speed resistor is burned out.
try replaceing the switch that controls the low to high for heater It's gonna be the blower motor resistor (near the blower motor).
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.
The blower motor resistor pack is bad.
You have a bad blower motor resister..........
Replace the fan blower resister
Most likely and bad blower motor resistor.
You most like have a bad blower motor resister.......
If you are saying the Blower Motor only works on high, then your problem is a defective Blower Motor Resistor Pack. Replace it.
replace heater relay and or heater blower motor
probably the blower motor resistor
heater blower resistor has to be replaced. you have to remove glove boxthe resistor is to the right of the heater blower moter
Probably the blower motor resistor, check blower motor at the same time
Most likely the blower resistor has failed. It is located under the hood in the side of the heater box.
bad blower resistor
I would guess a loose connection somewhere. Probably the blower motor. It can also be a defective blower motor resistor pack.
blower motor resister is bad
