Hi, Does the power stage resistor control the center direction air flow dial on the ECC unit? Or just the blower speeds? My dual temperature controls work just fine but the center air flow direction dial does not seem to work. Most of the air just comes from the foot area and a little comes from the dash vents. I am working the blower just with a toggle switch mounted in the glove box, since I have already removed the resistor. It works only on high speed with the toggle switch. Will replacing the resistor fix not only my blower speed control switch, but also that air flow direction knob. Or is that knob not working indicate a bad ECC unit?

The resistor only controls the fan speeds.It doesn't control the Air flow at all.

Thanks on the resistor question Tech. If the middle dial on my ECC unit that controls air direction flow was not working, would that indicate a bad ECC unit ? However the temp control dials (both driver & passenger) do work.
THANKS.

Not really the motors that open and close the doors could be bad.
ECC is all controlled electronically.

You might be able to see them but im not sure if you can get them out.

I have always had the dash out and relpaced them then.
