Have you checked the plug under the passenger side? The AC blower has a wire that burns until the connection is lost. Happened to my old H3.

I doubt it would cause your temps to be inaccurate, but it's worth a try.

It's probably not actually hotter, but I just had the ETC sensor changed and now mine reads cooler. Apparently there is some variance among sensors.
