Anyone ever had the HVAC system off and driving down the road, system comes on full blast A/C? It happens about once a week. If I touch the controls, it shuts off. It's analog, not auto climate control. If I don't touch anything, it eventually turns back off after about 20-30 seconds. I searched and didn't find anything on it. Searched manual to see if it is some sort of auto clean out. My commute is about 3 miles. So many days, I don't even turn it on and always turn off the system when I turn the car off.
