I can't get my heater/AC to turn off when I am done using it. It continues to blow air either out of the vents, or from the floor. Should I be looking for a vacuum leak?

on my 89 buick i had that problem.there was an electronic module that went bad.of course the buick was climate controled so it may be different.

Are you turning the slider to the OFF position? If the slider is anywhere but OFF, the fan will still blow even with the **** turned all the way to the left.

The slider is set to off and still getting air out of the vents, and or floor vents.
