It is a known issue on all C4's with the automatic climate control that the button contacts should be disassembled and cleaned as well as the electrical header on the main plug.

not your issue, but also want to mention that the operation of the early vs late programming on the chip is also different. I can't get a/c on the straight vent button on my 91, but it works all day long when auto is selected. My 95 worked a/c on any vent selection.
