The problem sounds like it is with your blower motor not your ac system. Restore multiple speeds to your auto heater air conditioner blower by replacing a resistor module. Nevertheless often when this component fails it suffers catastrophic heat damage. They do this for cooling purposes.

That s why they re not far from the squirrel cage itself. The air conditioner won t run properly unless your engine is running. Here is how to tell which. Swap in the new part and reinstall the screws and connector.

Most ac systems are designed to work within a large range of temperature variants and environments however due to numerous causes the air conditioner is still prone to overheating. These blower motor resistors get hot. Carac not blowing air from vents because of the following. The best setting for diagnosis is fresh air not recirculated with the air blowing out of the center vents in the dash and the ac turned on.
