Drivers side AC will blow hot air.

Dual air. The actuator is bad. It is between the fire wall and HVAC plenum. The dash has to be removed along with the plenum. Costly job at the garage.

The actuator that 'blends' cold with hot is stuck in the cold position. There are a couple of options. Disconnect the battery, then drive the vehicle around without using the AC for 10 min, if the AC is defaulted to come on after a battery interuption, then shut the car down then turn it on again. You are trying to get the electronic actuator to reset and resume proper function. Another option is to try this: Start the car, adjust the pax side full hot, drivers full cold, wait 30 sec then shut car down, then start car back up and reverse the settings, pax full cold, drivers full hot. In both solutions, the vent actuators are stuck at either the full open or full closed, so you are trying to get it to 'self check' and allow them to resume proper function. After two years, I simply removed them altogether since I live where it is hot an only need cold.works just fine....

This is a common problem when the AC system has a low charge.
If this is the case, you have a leak somewhere. Do not try to fix it yourself without the proper equipment.

On the passenger side of the engine compartment near the radiator you will see a coolant control valve that has heater hoses running from it to the heater core inside vehicle.This is probably going bad.You can clamp off the hoses with some pliers while it is acting up and see if this stops the heat.If it does then it is probably bad.
