how to repair heater, a/c system that switches from cool to full heat at will.

What is your question?

My a/c system switches to full heat while driving. It occurs on the drivers side only. Shutting of the engine and restarting will temporarily correct it. System is dual control. It happens frequently and without changing the temp settings.
