Hello all, my name is Cristhian and I have just registered today. I have been browsing here since 2001 when I had my lightning.

Well my question is: I have a 2004 F150 and yesterday it was 4 degrees here in Denver. I had my heater working fine all day. I got home from work and left the heater on. When I jumped back into the truck the heater did not blow any air out. Could it have froze??? I moved the climate control and I can hear something opening ( does sound kind of slow) but no a/c or heat. The other funny thing is that my temp. guage is usally in the middle after warming up, and now just makes it to the first line after driving it a while. Any feedback is appreciated. Thanks to all!!!

 

Great news!!! Sunny day today and went to start truck and heater started blowing. I'm sure not leaving the heater on after turning off the truck.
