[QUOTE=bdinis;3836888]Hey guys I have a 05 f150 lariat and the ac/heat is not working oUT of no where. ..air just blows out on high through the defrost vents and is cold...when I disconnect my battery for a bit everything will work fine heat and all but than goes right back to broken with in a couple minutes...any input on what it could be? Thank you[/
Seeing how it will work for a bit when you disconnect the battery I would assume it would be something electrical...does it make any sounds when you first turn on the truck or ac unit? I would just you tube my problem and troubleshoot from what what you find on there....thats how im learning on things....you may have a blendoor motor issue. ..hope I helped in any way and good luck.
