E32 Heater/AC control module 1989 735i

[bkopper]

Is it possible to remove the printed circuit from the above unit to resolder a burned out light bulb? Anyone succeeded in replacing a burned out bulb in this unit?

The cluster of three mode switches on the drivers side of my car doesnt light up. Middle and pass side are o.k.

Took module out of dash and removed control module and its rear cover. Plugged in wiring harness and can see three different sets of lights glowing. Can't figure out why the mode switch on drivers side is dark?

Reluctant to start pulling on circuit board since this whole assembly could pop apart and I'd be covered with all sorts of parts with no idea where they came from.

Any help/suggestions/success storys would be appreciated.
