The HVAC blower is not working on any setting: 1-5.
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
Thanks, just got the car for my stepson and fan was working great on all speeds. Stopped with no warning, no intermittent problems...
