AC Problem/Question

[Titomars]

Freon will not affect the blower or the vents. The Mode (vent) selection is vacuum controlled on your truck and the blower motor is electrical. all three are not interconnected to work. There are pressure switches in the A/C lines for low freon and for high pressure to cutout the compressor under certain conditions but they do not kill control to the panel inside the truck. If the modes are not working you most likely have a vacuum leak or your multi port valve at the control is not working. the blower could be no power to the switch, the switch, the blower resistor, wiring to the motor, or the motor.
