I know all about this car... When fan not blowing, I need you to do a few
test... Turn your fan speed to high.
1. Turn your ignition key back a further bit more without stopping the
engine, does it comes on? If yes, your ignition switch is bad.
2. If above not work, then with fan speed high... I want you to slap your
passenger seat lower dash hard... if fan comes on, then your fan motor
brushes is worn out.... need rebuild kit or motor.
3. If both above not working, then I want you to take the blower fuse out
and replace it with a new one.
