    So now it's cold in Las Vegas, finally, but now when we turn on the heater there is no air out of the front ducts and when I try to switch to recirculating air the light just flashes and keeps the fresh air lit up. Do I have a bad cluster? So that's 2 weird issues with the same temperature control assembly.

    Any thoughs? I just got my LMC catalog in the mail and it's part #37-1083 $249.95 ouch.

    My gut reaction is that it could be the mode door actuator that's bad.

    How would you fix that?

    The flashing is a code, if you can get a scanner to access the bcm or hvac system to read.

    You fix a bad actuator by ordering another one and removing/replacing the old one.
