. Air won't blow out of the floor or center vents just defrost ? Do you have manual or automatic climate control ?
Air Flow Control
Air flow control is accomplished in the following manner:
  • Primary control is through the function selector knob mounted on the A/C-heater function selector switch, which is part of the integrated control panel.
  • The function selector knob has the following positions: OFF, MAX A/C, A/C, PANEL, PANEL/FLOOR, FLOOR, FLOOR/DEFROST and DEFROST. The A/C-heater function selector switch combines a vacuum selector valve with an internal electrical switch.
  • The vacuum selector valve directs source vacuum to various vacuum control motors (18A318). Refer to the Vacuum Control Diagram , System Airflow Schematics and Vacuum Control Chart .
  • Two internal, single-pole electrical switches are also controlled by the A/C-heater function selector switch. The combination of these electrical switches controls the electrical supply to the A/C clutch and heater blower motor switch (18578).
  • The position of the function selector knob determines the manner in which the system will operate.
  • Each position of the function selector knob is detented for positive engagement.
  • Vacuum Control Motors The vacuum control motors (18A318):
    • are located on the A/C evaporator housing, A/C recirculation air duct and heater air plenum chamber (18471).
    • direct system airflow to the vehicle interior as determined by the remote climate control module or manual override.
    • The five-passenger seating configuration has an additional vacuum control motor mounted on the heater air plenum chamber to control airflow to the rear seat A/C register (19893).

My AC air registers only have air coming out of the defrost ducts

In every car, there are fins or flaps inside the dash that rotate that distributes the air flow from the blower to the desired opening, ie defrost, floor etc... This flap is controlled by a linkage which is connected to the selector switch. It may be the linkage is no longer connected, or the fins inside the dash are stuck. If the selector switch moves freely with little or no resistence its possible the linkage is no longer connected, otherwise the flaps need to be physically looked at.

The selector switch for dash air ,floor air doesn't direct the flow of air stays on windshield air only is there a relay or a diaphram problem?

Hi, sounds like a vacuum problem. When you select from floor to vent to defrost, the system uses vacuum from the engine to change over. If you look under the hood, near the firewall, towards the center, there should be small rubber vacuum lines. Check these lines for leaks with the engine on by spraying soapy water on the lines. If you see bubbles forming on any of the vacuum lines, this is where the leak is. Also check the vacuum lines going to the climate control unit inside the vehicle.

HVAC vent selector does not function. Air flow is

THe blend door seems to be stuck. When you change settings from defrost to floor air or, vent, the blend door opens and closes directing the air to the place you want it to go to. I have had some success spraying a lubricating oil such as WD40 under the dash on the blend door. You need to get under the dash with a flashlight to locate it. It looks like a flap. Spray it with a couple of shots of the WD40. Go easy on the spraying as you may be inhaling the fumes. Keep the doors and windows open to minimize the fumes. Wait about 1/2 hour and try the A/C functions. (defrost, floor, vent air)
