My 81 300D Non-turbo has some blower trouble. I replaced the fuse and pulled the blower out. I connected the blower to the battery to see if it turns and it works fine, no dragging or anything. I resoldered all the joints on the control unit. When I turn on the car, and push the EC button (or any button) the fan does not turn on. What do you suppose the problem is? Is there a control relay someplace that I can check?
Thanks,
Clint
