help !! the air condition in my car only works on high. Could it be just the switch?

IT IS MOST LIKLEY THE BLOWER MOTOR RESISTOR

DEPENDING ON TYPE OF CAR IS LOCATED ON THE OUTSIDE OF THE AIR BOX UNDERDASH OUTSIDE OF THEBLOWER MOTOR HOUSING

What kind of car? My wife's Dodge Stratus had the same problem. Her fan motor had to be replaced.

I should add that I put 3 resistor assemblies in the dodge, the faulty fan motor kept burning the resistor pack out.

There may be a seperate fuse for the high speed on the blower motor. Check the fuses first.

Probably the blower motor resistor.

Blower Resistor is burnt. It defaults to high.

i had that same issue. took it to the repair shop and found the motor for the lower part didnt work.

check all the fuses first and then if it's unbearable, get it fixed. it cost me like $200 to get a new motor put in.

it could be the switch, but most likely is the resister.

most lightly the switch
