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.

For the EATC electronic climate controls, there is a self test to do and codes will be displayed.

Interior temperature should be 40~90F
Ignition switch in the RUN position

1) press the OFF and FLOOR buttons at the same time.
2) then press the AUTOMATIC button within 2 seconds.

Watch display window for codes. report back.

To exit self test and clear all stored codes in the EATC- Press the defrost button, display window will light up.
EATC turns off. Codes cleared.

Always do this after the self test mode before turning off the system.

This quoted is from the 98 Explorer repair manual. Do so at your own risk.

I have the manual 3 knob climate controls in my 98.

Does the actuator move, the shaft rotate, when you adjust the temperature? You should be able to make it move with the temp setting. I have the blend door issue on two 98 Limited's, the actuator operates properly, but the door rarely moves at all.
