91 100 - heat works good and ac blows cold, but every now and then, the temperature resets itself to a higher level on its own. for example, today i had it set at 74 and noticed that the fan started blowing faster hot out the dash vents. it had decided to reset to hi (heat) when i was running ac. reset temp to lower level and ac came back as usual. anyone else had this problem? any suggestions?
thanks in advance

Either your car is haunted and the ghost(s) driving with you likes it hot or you have a bad climate control head.

selected. Are you saying that the number you selected changes to another number and the temp follows? Did you try going to ECON and seeing if the setting changes in that mode? You won't actually get A/C but it will just take in outside air and stop heat when trying to cool the inside of the car down. This is just to see if the numbers mysteriously changes while in another mode.

change happened in auto - temp reading stays same in econ.

type in the middle row. A circle with a dividing line and colored orange and blue. The ID no. is 443 919 578. Mine stayed on and sometimes would not work. Then stayed on all times. I opened it up and the windings were burnt. Worth a look?
