So my blower motor fuse keeps getting hot and starts to smoke i have unplugged the motor and it still smokes. I have also unplugged the temp relay and still smoking. Dose anyone have any idea what could be causing this ? Sorry I guess it does help to know what cari have . It is a 1983 300sd


So I have used the 16a fuse and that was still getting hot and smoking with the blower unplugged i have also traced all the wires in the eng compartment to the fuse block and all is looking good there. I have not unbolted the fuse box and inspected under it nor have i unplugged the speed control at the blower. Now if i am looking at the master cylinder it looks like the resister is under it. Can this be ? And can the resister be causing the problem ?
