I have a similar thing in my Olds, but that's a 79, so it's all vacuum. It could be a blender door or one of the myriad of electric motors that control the vents in these ever so complicated animals. Sadly I'm not qualified to make a more in depth diagnosis. Maybe someone else will chime in.
'94 STS heater problem
I'm hoping that you can help sort out our heater situation. :worship:
When we put the heater on the Defog setting, warm air comes out the by the windshield and the passenger footwell; but cold air comes out by the driver's feet, and the vents for the backseat.
The Defroster, Economy, and Auto settings seem to get warm air, (with the back seat vents still getting cold air); but there doesn't seem to be any way to get warm air to the driver's feet.
Any ideas?
