With winter on its way the heater is definitely needed. If the passenger side blend door actuator goes out it will cause this problem, I assume the driver's side is hot, correct? Here is the location of the blend door actuator so you can swap it out.
The Dual Zone heating and A/C system has two blend door actuators, one for the driver side and one for the passenger side.
Here are both the drivers' side and passenger side actuators so you don't get them mixed up. Also, you will need to remove the glove box and some ducting. Check out the images (below). Please let us know how it goes.
