Blower Motor Inoperative

Hey all, I'm new to diag​.​net I hope I am posting this in the correct place. Please correct me if need be.

So I am having trouble finding wiring diagrams for this car. Mitchell does not have the correct diagram. I do have a subscription to startekinfo​.​com but the information doesn't seem to be present for something that old. I also reached out to a local vintage Mercedes specialist for help which I was clear about paying for. I haven't heard back all day. So hoping someone out here can help.

I need the wiring diagram for the blower motor controls. The blower motor does not work. No voltage to the motor. If I jump voltage to it, it functions normally and draws 10 amps. Fuse #6 is labeled blower motor, and it has 12v running through it. No voltage found at the blower control switch or the resistor. Need to figure out where I've lost my 12v.

Thank you!
