Hey y'all!
I'm hoping y'all might be able to help me figure out what's going on with my husband's truck AC.
He has a 2011 F-150 Lariat 4x4 with the 3.5l EB engine, and the AC has stopped working. It only blows HOT air (like, as if the heat is on - hotter than ambient outdoor air), even if set to cold, and ALL (4) of the actuators click. We replaced the most accessible one behind the radio, and it immediately started clicking again, even after doing the recalibration procedure. This leads us to believe that the problem lies not with the actuators, but something that's controlling them.
We have confirmed that the compressor is operational and freon levels are ok.
Does this sound like it could be a faulty HVAC control module, or should we be looking elsewhere?
