    Default Blending Door Actuator Removal

    Howdy all -

    Need a little help. The door on my 86 won't open or close automatically. After further inspection, I keep hearing a hissing from the actuator. If I disconnect the little plastic piece on the door, the arm moves a little bit here and there and sometimes I can push the door closed when it's on max, but evetually, it pops back open. I'm gonna assume that there's a problem with the actuator. But how do I get to it? I've seen a couple of screws that are in there from the back and 4 larger flat top bolts, rivets, etc., that look like they hold it on.

    Any suggesstions would be GREATLY appreciated. Gettin a little warm down here and would like to cool the cab vs. just my feet

    Welcome to the site! I'm sure someone will chime in soon with the answer or you could look at the thread in the Q&A section titled "Repair Manuals" and after accessing the database you could do a search for the repair procedure for that blend door.
