November 16, 200718 yr hello all....i have a problem with something to do with my defroster....every time i press the button for my front defroster the AC compressor turns on....anyone else with this problem...by the way it is a 1996 subaru legacy with a 2.2 liter engine...any help or insight would be appreciated
November 17, 200718 yr Its supposed to do that. In the wintertime, the defroster will kick on the AC compressor because it keeps the system lubricated since you're not using the AC during the winter. I believe it also helps pull the moisture out of the air inside the car as well but not sure on that one.
November 17, 200718 yr Very normal, I've actually never owned an a/c equiped car that didn't do this.
