Problem found in 1986 560SEL

[esuitter]

I posted earlier about my problem with the temperature sensor aspirator blower (on top of the right side heat duct behind the glove box) running all the time - even with the key off! Further investigation found the mono valve on and when I unplugged the R side on the climate control several things clunked. Needless to say I also found the battery always going dead. After much skull work the problem was the group of leads from the climate control stuff (aspiraor, mono valve, etc) was connected to an always hot point in the fuse box and not to fuse #5 ckt 15.
