My A/C or heat will only blow out of the defrost and floor vents, and I can't figure out why.
The vacuum line was severed, so I spliced with vacuum line. However no change to ac blowing from defrost and floor vents.Check the hose on your Vacuum pump and follow the line to the firewall where it enters the cab, defrost is the default setting with out vacuum.
I will check the actuator asap.The vacuum actuator that controls that is right by the drivers right foot
