The aux fan in my 16 valve is not running. When I turn on the a/c, shouldnt the fan also turn on? The clutch controlled fan on the inside of the engine compartment engages and also engages into the high speed mode as when the a/c is turned on. However, the aux fan doesnt turn on. What can I do to test if the motor is bad? The fuse for the fan isnt blown. Thanks, Joe
