    No a/c when Idling, Engine heats up. Fans come on for a few seconds, but not very fast, then quits. A/C works when your driving fast enough to get airflow across the condensor.

    Fan continues to run after the ignition is turned off, repair shop said cooling system was okay, but for $85 they could connect it to the "computer" to tell me the same thing I just found out on the Internet, I will be calling Mazda to see what they have to say.

    Fan continued to run for some time after engine shuts off. Fan comes on and winds up as soon as engine is started.
    During summer Air would not cool car. Dealer said the module had already been replaced twice and they would not replace it again. If they replaced it it was without my knowledge.
