1. 1997 wrangler heat/AC unit

    Hi, my 1997 Wrangler I just purchased had the air comes out all vent, it cold but I want it corrected. What I found the “the Panel/Demist door actuator and defrost door actuator are tied together. It must have it reason to be tied together and if I remove I may lose my ac in the Texas in July. Ever see this being tied together or why? Thanks Tim

    On my 2005 Wrangler, the controls that direct where the airflow goes is vacuum operated. When You get a vacuum leak somewhere, it generally causes the AC to come out only the defrost vents. Is this similar to what you are seeing?

    Pic would be good.

    Possibly the door pin is was broken?

    Here is a write up on the actuator causing issues but a pic would give more in-site. Jeep Wusses - Quick Heater Fix - Jp Magazine

    Just for clarification. Air comes out all vents no matter what selection.

    Is the blend door and select door intact?

    Pics please
