FYI- for anyone who is having issues with the a/c only working in the max position and the heat blowing if you move it one notch off of the max air. This started after replacing the battery for me. I searched this issue throuh the forums and was ready to buy all new parts and then I tried this. I disconnected the battery for 5 minutes then I put all of the control ***** in the calibrate position:
Temp to the right
Fan to the right
Vent control to the left
I re-connected the battery and let the system calibrate. To my surprise everything worked fine. I don't know if this was a freak fix or not.
