Thanks Jim, I will give it a shot in the near future. My driver's side window developed a klunk as it goes down or up at around
1/4 the way from the top closed position. So I suspect the regulator, as my 300SE had the same symptom. (repaired by the mechanic).

I'll post results when it is done.

Denis
