Hello, sorry about my english Im Spanish.
My blower seems to be bad, first only 1 speed, now, no speed. In my country dealer sales to me 2 parts for this poroblem 1) 140-821-83-51 2) 210-821-15-51. I dont desarm or desmantle the blower yet. How should I buy? With 210-821-15-51 I have to buy something else? I see in tutorials that with 140-821-83-51 with some work and soldering I can fix It, What do you recommend for me? Thanks a lot.

I read that, so you say taht i have to put w140 part, not the w210 original part replacement? Hoy do I check If this part was bad to make shure? Thanks again

Your description sounds like the regulator and the regulator is the cause most of the time. As far as the part choice I think that pulling the motor and comparing it to the photos in the thread should help. After checking the part number on the motor and regulator, go to autohausaz and look up the replacement items. The listing shows which part numbers go together. Modifying and installing the W140 (S Class) part is a work around that is cheaper if you have the right style blower motor.

Hope that helps some.
