I've recently installed an in-dash evap/blower combo in place of the original evap/housing/blower on my w124...
the switch that came with the unit is a simple rotary 3 speed unit.
I want to be able to control the AC from the original push button control unit so I decided to open up the control unit itself...
It seems simple enough... I can isolate the illumination circuit and disable everything else, I will just use the switches themselves and eliminate the PCB circuitry altogether...
the pushbutton units themselves are like this:
there are 6 legs per unit... anyone know which is which?
I plan on using the 3 fan speed buttons as speeds 1,2 and 3
and 3 of the main buttons as ON, ECONOMY, and OFF
thanks guys
