I am going to attempt the heater core swap. I am not 100% sure if I have to discharge the A/C.

The vehicle is a 1994 Audi 90 Quattro 2.8L, manual transmission. Believe or not, the stock A/C still works and has never been recharged. When I bought this car 18 years ago the mechanic told me to expect the AC to go.

Thanks

When I did my Cabriolet I pulled the entire airbox..I needed to replace the vacuum motor for the recirculate flap anyways..and you need to pull the a/c side of the airbox to get to the part..

The answer is no, you do not need to discharge the a/c,,the heater side of the airbox is help on with clips that can be removed (the rear clips can be fiddly) and the heater core once the box is out.

Thank you for the reply. I was hoping I didn't have to mess with the A/C
