Question about AC?

Question

Hi, The AC in my car is working very good. But everytine I stop the car for 3 minutes due to traffic signal, it turns hot and the air increases in the instrument panel. When the traffic light turns green, everything change and the AC is cold again. My car is DAIHATSU materia 2008 Anyone knows whats the problem?

Answer 1

Sounds like the AC condenser fan is not running. Turn the AC on and the condenser fan and radiator fan should be running all the time.
If those fans are running check for debris in front of the condenser.

Answer 2

Make sure car is idling at the proper RPM. Check the electric cooling fan, to see if it is working properly.

Answer 3

sounds like your ac compressor or youre running out of freon

Answer 4

I agree with thebax2006 that it could be the fans . . . but:

I once had a small car with a small engine and AC: it was set-up so the AC compressor would shut-off when at idle or when going-up a hill. Of course, if you've had the car for some time and this is a new problem, then I suspect the radiator fan(s).
