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.
