Where have all the Benz experts gone around here and BW?? At this point, I'll even entertain a dumb idea! I do know, when someone has this problem in the future, and they will, these threads will prove valuable!

I installed another used temp reg box and now I have the compressor "on" signal at the klima plug. This is proved by having +11vts at pins 5 & 10. Only trouble is I got that with the push button box OFF! So I guess my box needs more work. :-/ Bought another push button box on fleabay. Fingers crossed as I fire the parts cannon at this sob!
And of course the clutch didn't engage. (Klima relay)

Where is my expert here that has built his own KLIMA that works??? Because the 3 boxes I have aren't worth a damn. One of them is going to get gutted for parts thats for sure!
