My air conditioning is not blowing cold air, I have had it checked for low coolant and filled. The problem is it blows a cold air out of the drivers side and warm air out of the passenger side. Does anyone know what the problem is?

 

Do you have any codes?
Most likely you will need a dealer to get deep enough into the car.

This is probably a silly question, but have you checked to make sure that the zone control on the passenger side has the temperature selected to be as low as on the driver side? I have found myself embarrassed a few times when settings were different.

 

Same thing I was thinking when he described his symptom. Unless set to sync, the driver and passenger side temperatures are adjusted separately. Now if they are set for sync and/or he adjusted the passenger side down to a cold temperature and it still blows hot, this isn't a problem with the compressor etc.(otherwise he would get no cold air anywhere). but more than likely either a stuck flap that is staying in the position to bring in air from the heater core, or the climate control module not sending the signal to put that flap into the correct position.
