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?

Re: Heating and AC question

That should not happen. with the last knob (position selector) set on off no air should come in. You have a poss 3 problems. 1- vac leak between engine and selector switch. 2-vac leak at the recirculation door servo. 3- bad selector switch.
Check all these first these are off the top of my head. if those are not a cause get back to me and I'll get a Ford manual out and do some real diag for u.
