    A/C and Headlight Problem

    Does anyone have any insight as to why my A/C will not work for 3 to 6 mins? The indicator on the dash is on and I can turn up the fan speed make it colder... but the air is not blowing. After I drive maybe a few mins, it will resume the status as indicated on the dash. Also at this time the headlights do not work. Any suggestions?

    Re: A/C and Headlight Problem

    The air isnt blowing, but your saying that you can turn up the fan speed?

    When you turn the air con on this has nothing to do with the fan / heater blower.

    Normaly one would need to turn the temp dial to cold and then turn the a/c on, although turning the a/c on may automaticly shut off the hot air supply.

    Based on the nature of aircon, the technology is the same principle as your fridge, you have a compressor on the engine which compresses a refrigerant gas around a sealed system, The compressor compresses the gas into the condencer which causes the gas to turn to liquid as it cools it then gets pumped through to the evaporator inside the car, as the air blows through the evaporator the heat gets absorbed out by the coldness of the liquid in the evaporator, and that gets taken back to the compressor and the cycle repeats.

    It may take abit of time for the system to get cold, and obviously the engine needs to be running.

    As for the headlights not working could be fuses, bad switch or wiring..

    It may be worth checking the fuses before checking anything else.....

    Usually the signs of a bad ignition switch.
