My 1987 3.2 has recently developed a strange noise under the dash near the center. I haven't gotten under the dash yet to try and find out where the noise is coming from and thought I would post here for some ideas. I have not checked to see if it still does it with the A/C off but will. It's starting to bug the crap out of me!

Noise sounds like a vent door of some kind opening and closing repeatedly. The sound would be similar to something rolling from side to side in the glove box.

Any similar experience? Any ideas what it might be?

(Note: car have the automatic heat & the underdash temp sensor & fan which appears to be functional but could be the culprit??)

Thanks!
