Well going down the road the other day I noticed my feet getting hot, but my body not. So I check the heater and it's off, so I put my window down for a few. Put the window back up and a little later my feet are hot again. I put my hand down there and I feel heat coming from the vent. Strangely though, I turn the Cold/Hot nozzle on the heater panel to cold and it blows out cool air...

Can I get a possible explanation, please?

 

Hard to guess without some info about the year of the car, but if its a 4th Gen the flapper doors that switch between heat/cold, and AC/heater are vacuum controlled. Either you've lost the vacuum to the flapper doors, or the actuator on the door is bad. Then again, if its a 1st Gen, it might be slipping actuator cables......

 

There is always some air that flows through, even when the blower is off (when the car is in forward motion). If the temp **** is on the hot side, then it will be hot air. If you switch the **** to cool, then it will be cool.

 

When you drive the air is forced thru basically it.

 

I didn't know there was still air that flowed through...

BTW, I have a 1998 w/ the 3.8
