Different Blend Door problem?
Hi. I have a 97 Eddie Bauer Explorer. The heat and a/c don't seem to be working properly. The heat isn't very hot and the a/c isn't very cold. I read the free blend door fix thread but it sounds like I have a different problem. When I first start the car the a/c works great and is very cold. After a few seconds a clunking sound starts coming from behind the dash. Clunk, clunk, clunk..............each clunk about 2 seconds apart. It does it on both heat and a/c. It sounds like a door is opening and closing over and over. The only way the noise stops is to turn the a/c or heat off. When you turn it back on the air or heat works great for about 15-20 seconds then the clunking starts up again. Any ideas what it could be?

By pressing & holding certain climate control buttons you can put the system into self test mode.
If the self test detects a problem, trouble codes will display on the dash readout & if the actuator that Hank mentioned is bad it will display a trouble code.
Heres a thread that might help http://www.ford-trucks.com/forums/sh...+climate+contr

I'm not sure how to check it out but I know it was a pretty easy fix (compared to the doing the plenum).
