I have replaced the following: Blower motor Blower resister All pannel switches and thumb wheel (temp. setings). All fuses and fine. The AC compressor comes on but not blower. It does not work at any sittings. What should I do next to make it work.

I'm not a Mercedes expert, but I can say that a blower motor draws an awful lot of current, and as such, the wiring for it can get overheated and damaged. Did you check the wiring at the motor and resistor when you changed them? Check for melted or damaged terminals.
