This morning after running the car for 2 miles, my car was still blowing freezing cold air. I messed with the temp knob moving it all the way cold to all the way hot a few times. Then I started to get warm air. It happend again tonight. This time I had to turn off the car and turn it back on again. What could be going wrong? Where do I start?
This is on a '98 Chevy Malibu.
