    Car shakes when fan is turned on?

    My '99 Mazda 6 violently shakes when I turn the fan on, I can see the RPM jumping. This shaking will stop after a couple of seconds and the car will be calm. Also, after installing my new head unit, I've noticed a more "noticable" vibration/hum in the car that I think is related to the shaking. Any ideas on whats going on here? I'm thinking about replacing the PCV valve, cleaning the air filter, and checking the spark plugs.

    I assume it is an electric fan? Bad fan causing stress on the elctrical system/alternator?

    What fan?..Cooling fan? A/c fan? If its cooling fan then it could be your fan clutch or fan module going bad...if its a/c then it could be your compressor or comp. clutch /field going bad.
