Hi Benzmatic and Panda, thanks for the help. So far I have removed the ACC unit (without damaging the wood panel!!!) disconnected all the console switches (signal lights do not work because the 4 way switch is disconnected), but I can still drive her short trips to the Auto part store in second gear.

Looked high and low for the "strip fuse" you mentioned and this car just does not have one, that I and a friend can find!!!
She is a w126 1983 SD turbo, and that darn fuse is nowhere that I can see. I have Benzmatic's pics on file and mine of the fuse box area are here, they are not the same.

So far for the heater problem, in addition to the above, I have removed and cleaned the Monovalve, it is OK, diaphram intact. Have found the auxilliary pump under the Monovalve hoses, blower fan works on the bench AOK. Somewhere, there is a power problem to activate the whole thing and I cannot find it.
As to my Tranny problem: I have replaced one of the two 3/2 vacuum switches on the valve cover and replaced the broken "plastic flapper" on the second one (both were broken) and tranny still does not shift to 3rd. Any suggestions? Next step here is a tranny job and there is a local good one.

These two problems solved and I have a daily driver for the first time since 1972 (been without my own since then) for the grand price of US$810. + parts & time, and a trip to NY and back to haul her home.

I cannot seem to get the pics to load here but will e-mail to benzmatic direct
Thanks Dick
