[quote name='taporite6' date='Apr 17 2006, 02:28 PM']it seems that when i close the vents on the side and middle of dash i get heat I had a mechanic look at it but he could not find anything wrong.The heater control unit seems to work fine. I should not get heat in the car with both controls off.
i replaced heater control valve and also checked if anything is loose under driver's side dash. any suggestions? it is driving me nuts.

Under the center of the lower dash ( right of the gas pedal) there is a box like plastic cover with a couple of screws in it, behind it is the linkage to the heater doors, more then likely one of the clips broke and the linkage is off and not moving the door. That was my case, clips are a couple of dollars.
