420SEL A/C

My 420 SEL has clicking noises from the vacuum switch over valve. Cold air comes out of center vents whith heater on. All vacuum servos are holding. I suspect the pushbutton controler! Thanks

RE: 420SEL A/C

I want to know if you fixed this problem? I have the same issue with my 400SEL 93
