the heater fan resister,it is or should be on inside or on outside heater box.
Yes, located in the blower motor resistor pack. Follow the wires backward from the blower motor to find it.
Probably the blower motor speed resistor is partially burned out.
Heater blower resistor is what controls the low medium high speeds...
A bad heater blower motor resistor would effect one or more blower speeds other than high.
Its not the relay, it is the blower motor resistor.
blower resistor especially if its chrysler/jeep or blower switch
Resistor on the heater blower motor has failed
Blower wont work on all 5 speeds, usually the lower speeds tend to go first.
The blower motor resistor is defective. They go bad when the blower motor pulls to much amperage.
You have a relay located behind the glove box once removed to the left and you also have a blower resister that controls the speeds located on the passengers side in the blower motor housing..............
replace the resistor pack on the fanblower, under glowecompartment
Only for the high speed blower function. The lower speeds go thru the blower motor speed resister.
