My truck's A/C will be blowing cold air and the all at once, it will start blowing hot air only on the drivers side. The passenger side remains cold. If I turn off the ignition, and then back on, it blow cold again. What is going on, and how do I fix it?

You're having an issue with the blend door actuator for that side of the control head that operates it. You will have to monitor what the actuator is doing visually.
