Q: Blower motor does not work on 1992 Mercedes-Benz 300E

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
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.
