Question squelch a squealing vacuum servo?

My 126/ '91 350sd has an intermittent squealing noise coming from a little round plastic casing with a small fan spinning inside it that is connected to a vacuum line ( I think) on one end and a padded small metal housing with a powere supply on the other end. This is right below the glove box on the far right side. I can stop the squealing noise by stopping the fan from spinning in its plastic case. Now that I have finally found this %#@&**%! noise can someone tell me what it is, and how to fix it. I think it mingt have something to do w/ climate control and regulating the vent in the rear of the console as I noticed that when the heat is heat is flowing w/ fan on in the front, that cool air is coming out the rear vent? thanks
