Is the airflow stopped or is it only cold air coming out of the vents?

The fuse is good but the blower motor does not work at all, if you touch the motor you can feel it is warm. Am in the process of check for power to the motor.

Thanks

If the motor is warm it's probably receiving power. If you can verify that power is there, take it out and see if it spins outside of the cage. It's possible something is not allowing the blade to spin. If that's the case you don't want the thing to run a long time.. it may burn it up.

Was about to take it out when I taped it with a wrench just to see if it would go and sure enough it took off. Left it run for about 30 min and it works fine now. Not sure what was going on, maybe from lack of use.

Thanks

Front blower

did you check the front blower for voltage? Should be located under hood near passenger firewall. They usually don't just quit, it might be blown fuse or bad switch on your dash.

Check your ground

You probably have a dirty ground connection to the fan. One of the screws holding the fan in should have a ground wire connected to it. Take it off and scrape it clean for good ground connection.
