Question about Cars & Trucks
If the heat and a/c only blows through the windshield defrost vents, it the mode door that is not working. Has nothing to do with the freon in the system. 1986 models may use a vacuum operated mode door actuator or an electronic actuator. Most likely, vacuum. Do not know the exact location, but it is under the dash. May have a vacuum hose loose or the actuator itself could be bad.

Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.

I have the same car and had the same problem. The inside air intake for the heater system is located above the passenger's feet. An empty plastic bag got sucked in there and kept the door from moving properly. I had to take off a few panels, then one on the vent. Once I removed the bag, no problem.
