Why Is My Car Ac Blowing Hot And Cold Air. Your car ac is actually a heat exchanger that recirculates warm air from inside the cabin and replaces it with cold air. This occurs due the evaporation of condensate back into the air stream, when the compressor is off, however the blower is on.
Your car ac is actually a heat exchanger that recirculates warm air from inside the cabin and replaces it with cold air. Other common reasons include electrical issues, a faulty condenser, broken cooling fans, or a bad compressor. Generally speaking, a lack of refrigerant is the most common cause of your ac system only blowing warm air.
If This Is The Case, Be Sure To Take It Into A Mechanic As Quickly As You Can.
The fans could actually be broken, like a burnt out motor, bad mount a chipped fan blade, or they could simply have an electrical problem like a blown fuse or burnt out relay.

You’d Be Roasted Inside The Car Considering Our Country’s High Temperatures And Sunny Days.
Your car ac is actually a heat exchanger that recirculates warm air from inside the cabin and replaces it with cold air. Any time you lose refrigerant from your car’s ac system, that leak allows air and moisture to enter. The most common cause of an ac system blowing warm air is a lack of refrigerant, though, you may also have a problem with your condenser.
This Situation Can Be Caused By A Bad Blend Door (Also Called Air Mix) Actuator, A Broken Or Binding Blend/Air Mix Door, Broken Linkage To The Blend/Air Mix Door, Or A Faulty Hvac Control Head Or Wiring Harness.
Refrigerant that's in a liquid state makes its way to the evaporator, where it boils as warm air from the cabin flows across it. Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system. Like having a blocked condenser, having broken cooling fans can cause a lack of cooling at your condenser and could cause your car ac blowing hot air.
