There are speed control electronics built in the blower and these might be faulty. The red wire should always have 12 V DC on. The speed control system completes the path to earth with a supply voltage lower then the 12 V. If you remove all connectors, and connect spade connectors to the top connectors direct to the carbon brushes, the fan should run at full speed.
I will try and get the motor to run using this method to see if I need a new one or a fuse box...... I already have some parts from Scotty for other "problems". I would rather not replace the motor if it is just the fuse box, and the motor showed no signs of failing before it quit (other than quitting.......)
Can you post a picture that shows what pins need to be either connected to power or ground? I don't want to fry any sensitive electronics in the speed control mechanism, but I want to narrow down my fault, so any diagnosis I can do with the motor still on the car will be helpful. I am not sure where the voltage from RL-7 goes into the motor to see if this is the fault....
