Or at least I don't think so. I thought I had the typical broken blend door issue on m '98 Limited and ordered a new one along with a new accuator while I was at it. Before I took the old accuator off I set the temp to 90 on auto and thought I recalled seeing the shaft turn. "Aha! It is the blend door!" or so I thought. I disconnected the old accuator so that it wasn't hanging from the wires while I waited for the new one. The new one arrived, I connected it and nothing on any setting. I reconnected the old one and nothing. Before I started cutting the plenum I took the truck to the local A/C specialist and he suggested getting a factory accuator as the aftermarket ones are often defective. For $35 why not? While I was waiting for that part to come in I decided to see if I could move the blend door by inserting a hex wrench where the accuator shaft goes. Bingo! the door moved easily and the A/C is now cold again. The factory accuator came in and that doesn't work either. I am now second guessing myself as to whether I ever saw the old one move in the first place. What "upstream" of the accuator could be causing this? There must be a thermostat somewhere. Is it behind that little vent on the dashboard? Anything else that commonly fails? I can live with it the way it is now but the heat in the winter might be a little more difficult to fine tune with a hex wrench. Thanks in advance.
