On 1985 500sel- the AC/Defrost/vent works fine until the car
sets in the hot sun-then its dead. That is the AC compressor comes on but the blower does not engage. So it works fine on the way to work but not on the way home when it would be wonderful. Could it be the push button control and how does one get the face plate off to get to the pbc.
A simple fix would sure improve my life( car driven by frau)
