I'm working on my son's car. When using the A/C the air coming out of the driver side vents is ice cold, and the passenger side is hot. I know its full of Freon, and feel like it must be a problem with the doors of the vent system.
Does anyone have any tips on where/how to trouble shoot and repair this?

Thanks

If it has the dual zone its the temp. door actuator. If not it could be slightly low on Freon .

It does have dual zone.
Do you know where that actuator is located and is it controlled electronically or by vacuum ?
