OK, so everybody talks about resoldering the climate cotrol units. Yet all the specific instructions I find are on the w124.

I've got the unit from our W126 in front of me, and I am puzzled as how to get the IC board out. Something seems to hold it in place.

Of course, you could risk the entire unit and resolder from behind without removing the board. But I have a problem soldering diodes and other components I can't see (transistors? ICs?) without using a heat sink! I need to remove the board.

Honestly, had anyone actually done this on a w126? I am beginning to wonder about the accuracy and veracity of following this route.

Any advice appreciated.

Thanks!
