88 560SL ac center vent -- update please Steve

Steve thank you for the pictures

I started to look around under the dash

I do have vac to the system

The outside vent is working in both directions, it opens as the system cools down and will close when you press the toggel switch -- when I turn the wheel to HEAT the system turns the heat on and opens the floor vent on the right footwell.

I do not get any air from the center in AC -- the defroster stays on all the time and I do not get air from the driver floor vent on HEAT-- air will come out at the driver door port when I turn the dial to HEAT.

I replaced the pushbutton about 4 or 5 years ago - kima about 3 years - new comp manafold -- 134 changover and associated parts last year -$$$

I guess I will take the center off and look around. On the pictures please tell me that the diaphram for the center vent is not inside the box ! Any sugestions on what to look for -- I do not hear any leaks but then you may not be able to.

Thanks all

well I am still looking around inthat dash -- I have an old pushputton unit that i just tried - no difference.

I can only assume that the pushbutton oks I switched it out thinking it was bad years ago -- that was not the problem -- tought me a lesson -- just buying parts is $$ and often you buy the wrong ones.

I really do not want the dealer to be in the dash -- as it os all getting old and I am very carefull --- my dealer is very good though -- I am sure all know what i am talking about --

PLEASE

Is it true! - no one knows enough about the system in this car -- I would like to find the answer without having the dealer rip the dash up.
