Fan:
Put your mind at ease, It's doing what it should.

A/C turns on the driver side A/C fan.

If you want a hot test, cover the radiator with cardboard and don't let air move through the radiator; the fan comes on only when it gets up to a certain temp. If driving, air goes through the radiator, and the temp
MAY NEVER get up to that certain temp.....about 180 degrees.
The Fan will cut on when the hot motor is turned off, and water stops circulating through the radiator, and the temp gets up again.

I hope this was useful to you.-Bob
