1995 s500 (w140) Climate control

[Eric Pratt]

I am getting the following error codes:
E006 E074 E075 E082 E083 E086 E087 E102 E103 E106 E107

I sent the climate control unit to Programma Inc, the charged $399, said the unit had Bad Memory in the code and needed to be cleared and reset.
In addition there were lamps that needed replacement. They said that the unit tested good after their repair.

Today I got it back, hooked it up and I still get the same exact error codes.

I also checked the voltage going to the connector that plugs into the switchover valve block Y11

with Negative to brown terminal I got
Grey/Red terminal 0.56 volts
Blue/Yellow terminal 2.57 to 2.98 volts
Blue/Green terminal 2.11 to 2.50 volts

Are these normal values?

I love this car but it is quickly turning into a money pit.

Anyone have any idea what to do next???
