I'd be looking at a vacuum control line that's leaking, that controls the blend door. Hopefully someone with a better Vacuum Diagram for your year will chime in and post it. Here's what I've found:

Since you've been asked politely to stop using caps lock, I will explain why. Online, using all caps is considered shouting and is rude. Besides, it's harder to read. Please, please stop using all caps.

There is a ton of info in this forum, some with pictures! Check out the vacuum lines as LEVE said and X2 on the CAPS. If there is a reason for caps all the time, please let us know.
