I think the in-car temperature sensor is located next to front
overhead/map light and sunroof switch? I know that's the location for
my '87, haven't dug into the manual yet for this car. On my '87, the
test is to apply a square piece of paper 1 cm on each side and see if

For W124 I think you are correct. Sometimes my brain is stuck in the W116/W123

Not sure about your car, but generally the idea is to have everything fail to
hot defrost for safety's sake. That would mean normally open on the monovalve,
closing with power.
