What kind of whacky AC/Heat issue is this?

Hi have a 2001 Dodge Ram 1500 sport.

I have dealt with this for the last year or so but want to fix it now.

ISSUES:

1) My AC does not work. The fan blows strong but only heat, even when AC is selected.

2) My heat does not turn off. It is always on and blows harder when I accelerate aggressively.

3) The fan only blows from the floor and defrost, not from the dash.

4) I burn through coolant really quickly. There is no leaking. It just evaporates or something. I can smell it at times when running a full reservoir.

Help super heroes of the ram forums.

Heater core has a pinhole leak. That's where your coolant is going.

Heat thing sounds like a vacuum leak and blend door failure. What sucks is more than likely this is inside the dash. Less ****** part is you'll be in there anyways to do the heater core lol

I would guess there is more than one problem. Low vacuum (hard accell) will equate to the default setting of defrost as well as a vacuum leak. As for leakage, heater core or even possible head gasket? Good luck and let us know what you find.
