I'm asking questions all over this forum and getting great answers!!

Just purchased a 1981 240D with a 300TD swap, its a manual 4spd car.

The switch controls above the large three fan and left/right temp controls I need a little help with.

Going left to right does anyone have a picture of them and the operation controlled by them?? or just a picture of the symbols themselves that can be in place on these buttons and I can probably figure them out.
