I just recently replaced the control panel with a new one from O'Reillys, might be a Dorman. Everything works but when I commanded it to heat it began to warm then turned cooler over and over with the temp setting full hot. Since I've never changed the actuators on this old rig I assumed it might be one going bad. I just couldn't imagine it running back and forth temps own it's own.
I don't have either of those scan tools, just an Innova or something that only reads generic engine codes. When I get it back I will fiddle with it some more. I just had the A/C leak repaired too.
That roof sensor has a little fan doesn't it? Seems like I used to hear it buzz when the radio was turned down. ?
