After reading the many posts concerning the climate control systems on the 123/126 chassis mercedes I must thank everyone who has contributed.You have saved me countless dollars and taught me a great deal.Currently,I am trying to repair the recirculate mode om my 1985 300sd.The dual actuators work fine.there are no vacuum leaks.I have tried both a rebuilt ccu and my spare.they both work,and all other funtions of the climate control work well.what I have discovered is there is no voltage at any time to the #6 vacuum switch(in the bank of switches near the transmission tunnel)My question is. where does the voltage for this two prong connector come from? how can I repair this problem? thanks.
