OK. So my experience with computer troubles is always ask "what did you change last". Had the Service Engine soon light appear, had the codes pulled and replaced the appropriate O2 Sensor. This morning driving to work, I thought the interior was a little warm but .... When I went to lunch, yup, only hot air blowing out of the A/C and I didn't hear the compressor.
So has anyone had the same experience or is it just coincedence?
