Thread: a/c works early then shuts off

    Default a/c works early then shuts off

    I have a problem where the a/c works initially and then does not blow cold. I had the system checked and the levels seem to be ok....any ideas...it gets quite hot...lol

    It seems that it works for about 10-15 minutes and then does not blow cold. Once the car is cold again...a/c will work for 15 minutes.

    Thanks

    Any good A/C shop can find the temp/pressure switch and replace it. This is not brain surgery. There are sensors and switches in every A/C system to prevent over pressure. They often go bad.

    Go to an A/C specialist, and tell him what is going on. It should take maybe 5 minutes to diagnose. Probably not much longer to fix.

    I had pretty much the same problem except it would only stay on for a few minutes then the indicator light on the switch would go out and the compressor would stop cycling. The fix turned out to be a new thernal sensor/switch, but it is a real bear to get to.
