2003 Mitsubishi Lancer A/C

2003 Mitsubishi Lancer 2.0 4 cyl.
When driving a/c works great and super cool but when you stop it gets very warm,almost hot air comes out.Then after you get going again it starts cooling off again.

There are two possibilities. One is a worn compressor which can't do its job unless running at a higher rpm. The other is the air flow through the condenser.

The latter is the most likely.

With the car parked run your rpms up to a moderate level, but don't over rev the engine. Does the air conditioner start working properly? If so the problem is in the compressor.

If not the problem is in the air flow through the condenser. That would be the little radiator looking affair in front of the radiator. Check it for obstructions, but you probably have a cooling fan switch acting up.

When you are checking with the car parked, open the hood and see if your engine cooling fan (it may have two) is running. If not, you would have no airflow through the condenser = no AC.

The switch could be AC specific or it could be built into the engine cooling system.


Hope this helps,

Bob
