I have an 09 2.4L G6. About two weeks ago I noticed that my AC wasn't working and the check engine light came on along with the temp needle not registering. My cooling fans stayed on constantly from key on. It would sometimes come back and fix itself. About a week ago, I went to run some errands. The car started up, went to my first location and turned it off. Started right back up. Went to my second location, did the same thing. Went to the gas station turned it off to pump gas and when I went to start it - nothing. The odometer read error. Can the ECT cause this error. The shop said it could be a bad ecm that I would have to take it to the dealer. And can a bad ECT fry a computer. I know my starter works because it turns when I ground it out at the relay. But I don't hear the relay engage when I turn the key. Any ideas would help.
