I'm assuming that you have the three dials with the air con & recirc switches on your car & that you would like to change to the climatronic panel. It is possible but the costs would probably out weigh the benefits due to there being three temperature sensors, a sunlight sensor & a completely different wiring loom involved. Obviously it's also quite labour intensive. I've got the diagrams for both systems if you fancy it, but personally I prefer the dial layout to the climatronic panel anyway. It's easier to use, easier to change temp & fan settings whilst driving & there are less problems with the A/C compressor clutch falling off.
