The piece I was referring to in a previous reply was the check valve. I was wondering if this could might be the possible problem I am having. refer to previous postings.This check valve is in the vaccum lines from the plenum and teeing off. All the lines seem to be fine. I haven't looked under the dash yet.Speculating on replacing this valve before I go in the dash.

Just add (reply ) to your original post. Starting a new post everytime just confuses everyone to what you are talking about

I replaced the check valve and it helped. I still have cold air coming out at my feet. On the abs the control module has been replaced before I purchased the car. It also had new pads put on. Is it possible the brakes need bleeding due to the fact that I can feel movement in the pedal? I only get the movement once while driving. The movement is every time I cut the car off and then start it to go again.
On the cruise I turn it on and hear a clicking noise on the diaphram.Any suggestions? I know I have power to the unit.
