I have a 2008 1500 4x4 4.3 V6 with 40000miles. Recently the ENGINE HOT A/C TURNED OFF warning pops up, but the engine isnt really hot. It seems to reset itself after a while. I though it did it more in wet weather, but today is dry (though yesterday rained). It did this yesterday. FIrst i disconnected the temp sensor on the left head, then reconnected it. It looked clean. This did nothing. Then, I disconnected the battery, and when i reconnected it 20 min later it was back to normal. I drove about 20 minutes twice today, at the end of the second trip it did it again. There was a recall to remove the insulation from the under seat computer, which i had done. It had the problem prior to this, and still does. Its probably occurred 10 times in the last 6 months, 7-8000 miles.
DO i justs need a temp sensor, or is it possible more involved?
thanks
Sean
