Heating and AC question
I have a 1992 FS Bronco and I am trying to see if my heating and air conditioning system has a leak somewhere.
When I place the knobs to the following settings:
Knob 1 - One notch to the right, (or 1/3)
Knob 2 - set all the way to heat (I do think this knob matters)
Knob 3 - OFF
When I am traveling down the highway in my Bronco, there is still quite a bit of air blowing out of the four vents in the dashboard. I was wondering if this is suppose to happen and if anyone else's Bronco does the same thing?
