Check the fuse link..common on a car that has sat...

Arthur,

Thanks for the suggestion. I was planning a service visit soon anyway and was just going to have my mechanic look at it but a quick peek might save everyone a bit of hassle.

Should be over by the drivers side strut tower..little back box with a fuse link inside..they get a hairline crack you can't see, but if you jumper it and the blower comes ON , that is the problem

I would just replace the blower motor (Behr) and be done with it...the fuse is an 80 amp...by far the largest I've ever seen on a car. I just went through this with a 1990 300TE and actually pulled a used blower from a 1993 300E that cost me $15...problem solved...good luck

Where did you ever see an 80 AMP blower fuse on a Benz Cliffie...????

More likely mis-reading an 8 for a 3 in 30 AMP b/c his car is GAS.
