    Question New electric bug issue

    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.

    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.
