1993 W124 E280 - Aircon - Faulty Duo Valve

Here's a possible cause for a common problem - the aircon blows cold on one side, but not the other.

In my case, the passenger side was cold, and driver side was hot.

Electrics work fine, and I had the R134a topped up. It was at 30% volume.

Wiring was corroded on one side, and there was a split in the rubber seal.
