A/C Question

Ok, so I think I've got something going on with my A/C...

I am under the assumption that when i have my A/C set to blow out of the dash vents only, that NO air should be coming from the floor vents.

No matter what setting I have my air on, air comes out of the floor vents.

Any ideas? Hopefully I can find an easy fix that doesn't involve dismantling the dash, lol.

The amount of air coming out of the dash vents feels about the same as the amount coming out of the floor.

I would think that no or very very little air would come out of the floor when the selector is on dash only, then it'd be about even when it is set to dash/floor, and then no to very little air coming out of the dash when it is set to floor only.

Re: A/C Question

Ok then I think I know enough to say yes this is a problem. My jeep has very little coming out when changed to floor only etc. . . . but it does make a quiff noise while changing from each.

Re: A/C Question

Yeah... when I turn it to all floor, it all comes from the floor - so it seems that the only problem is when it is set to all dash and it blows out even from the dash and floor

I'm gonna go mess around with it a bit right now.

Re: A/C Question

Do you have the dual zone ac ?? If it's electronically controlled, one of the gears that operates the vents could be broken ... ???

Re: A/C Question

Black - yes I have the dual zone A/C - where are these gears located? I'm assuming they are a bitch to get to.

Just went out and messed with it - here it what is does:

Setting - Result

Dash only - dash and floor equally
Dash and floor - dash and floor, a little more air coming from floor than dash
Floor only - floor and defrost equally
Defrost and floor - defrost and floor equally
Defrost only - defrost and floor
Auto - dash and floor equally

Re: A/C Question

I'm no pro but I would guess that your blend door that leads to the floor ducts is broken..

Hmm, I think mine blows air through the floor vents too. I know my old Jimmy used to.
