That was exactly the problem in my 450SL. Only the intermittent did not
work and the wipers would not self park. Problem was that the cable
plug was disconnected from the control module. I suspect that previous
owner was trying to shoot a battery drain problem as several other
plugs were also disconnected on the car.
I'm not familiar enough with the SL you have to say of an easy
way. But, if you drop if off here ar my house, I'll seuss it
out fo ryou and by fall we'll now for sure. Aww hell, I'll jsut
fix it for you nice guy that I am.
Common sense says take it off, and apply a voltmeter. With the
schematic you might/should be able to find the wire that signals
intermittant operation and check that out with a voltmeter.
