Hot air blowing out from foot vents.
On both my 93 and 96, when I am driving along there is hot air blowing out from the foot vents, even when the climate control is off and not set for the floor vents. This has been happening for several months now and for a long while on the 93. It seems that air from the engine is making its way inside the cabin through the floor vents. How do I fix?

seems like u had the same issue i was going through...
I had to fix the air mix door behind the dash. its a little door that switches from hot to cold with the electronic climate control. cost me about $800 at the dealership had to completely remove dash and center console to get to it.

By design of all of the duct work, there will always be some air coming into the cabin even if the climate control is turned off. This air enters via the outside cowel inlet and travels to both the floor and defrost vents. Since the blower isn't operating while in the OFF position, the amount of air will be unnoticable during slow speeds or at a complete stop but can be felt under normal driving conditions. Since the incoming air passes by the air mix door, it will be heated or cooled according to the last temp setting. For instance, if you select 90 on the ECC head then turn the climate control off, the air mix door will remain in the "full hot" position and therefore warm any air that passes by it. If you select 60 and then turn it off, your little piggies will become cold on these chilly mornings as the air mix door will now be in the "full cold" position. The manual climate control works the same. If you leave the dial set to HOT, what little air is coming in will still be heated.
The air mix actuator would be to blame if you select a higher temp and cool air comes out or select a lower temp and the air is still hot. We get many of these topics as the seasons change.

Wouldn’t it be nice to be able to select whether airflow is from outside or from inside (recirc.) with the flip of a switch. Easy to do on my 96 Regal but not sure how difficult for a Bonny.

I could be barking up the wrong tree here, but how well does your ECT gauge work? Does it indicate proper operating temperature? Do you have any check engine codes at the moment?

No codes whatsoever.
ECT? Dont know what that is, but temperature for climate control seems to be working just fine. I am getting a code for HVAC but thats because I pulled the battery out on the 96 and I haven't got around to getting a replacement actuator (I need the part number).

From my first read through I was wondering how much air is really coming in?

On the 93 its as if there is a 2 inch diameter hole whle driving at 45 mph. On the 96 its the same. Climate control was completely off but it still feels as though its set on low. I had to take off my jacket while driving or open the windows because it got so hot.
