It comes on in the "on" position. My car never overheated and still does not. I have had the thermostat housing and sensor changed and it does the same thing. Because of the light it has disabled my speed and air. The car runs idle but that’s it. I have tried several methods to reset the computer. Any help will do.

Hello,

This is common when the A/C system is slightly overcharged the computer is alerted via the high pressure sensor and the warning given. can you try to drive it with the A/C off to see if it does the same thing? Here is a guide that shows the pressures and how to test them:

Hi Aaron,

AS far as the thermostat, is it for the same year, make, and model listed above?

Let me know. Also, confirm the engine size.

Take care,

Joe
