I checked the end of dash 20 A fuse and even replaced it. Still no fan. What's next?

Speeds 1-4 are on a separate fuse and power goes through a resister. Speed 5 gets power from a fuse in the engine compartment fuse box. Since the motor is not working on any speeds 1. it could be both fuses are blown. 2. it could be the motor brushes are too short. 3. it could be a bad ground connection. ---- Check the speed 5 fuse first. If the motor doesn't work with a good fuse, remove it and bench test it. DIY instructions can be found on GAOwnersClub.com
