But a system that is 1/2 pound low will cause the passenger side vents to blow cool or cold air, and the drivers side to be less cool or even warm and this car. There is simply not enough freon in the system to cool the air to the drivers side. If it does have dual zone, then the drivers side temperature actuator motor has failed. This actuator controls the temperature door for that side. Dual zone systems have a temp door for each side. - Visitor
