I've been having an ongoing problem with my heat controls in my FD. At first none of the selector controls worked with the exception of blower position four(4). I found a short in the blower motor relay that fixed the mix(temp) and recirculate/fresh air button. I still have no mode control and only position four on the blower switch works. I have tested all the big wires for continuity, swapped out the resistor and the control unit and it makes no difference. I have not hooked up a/c since my swap, but I don't think that would make a difference. Anyone have any ideas where I should be looking/testing next?

 

bump, anybody?
