w126 280se climate control
I posted last evening that I was encountering the same problem with my 1995 E320. Today I talked with my MB Tech and he says that in 90% of the cases on vehicles over 100,000 miles, but under 200,000 miles, it is the blower regulator that has failed. He said it probably is not the blower intself unless the car is over 200,000 miles. I am taking it in for service tomorrow. If it is the blower regulator I will get out for $550 USD.
