So imagine the temp knob not having a good connection, and you go over a bump with the climate control off, then the vibration may cause a connection spike in the temp knob, falsely telling the control that the knob was touched, and it turns on.

The solution is to clean the connection inside the temp knob a bit. The way you do this is by simply turning both knobs back and forth a few times. Then leave them in what feels like a good click and turn off the climate control. This should keep the climate control staying off for a good amount of time while you are driving top down.
thank you will give it a try.
