My heat works awesome...when set to 85 degrees. Turn it down to 84 and under and it blows cool air? :confused:

Do the heat/AC self check outlined in the AC section of the FSM, page HA-29. It should tell you if there's a bad sensor.

I did try that since I posted this thread. Only issue was intake sensor?

With the glove compartment removed it looks pretty easy to replace. See page HA-50. I wouldn't be surprised if the probe is just gunked up. Clean the tip and see what happens. Good luck.
