2nd Gen Non-Engine/Transmission A/C blower quit working

My blower quit working recently. I have checked the fuse under the hood and the one inside the cab and both are ok. Any ideas where I should start looking next?

The motor is "run" by a relay in the PDC under the hood, good place to look next, see if the motor will run in any speed setting, could also be the resistor. bg

Also swapped out the relay for the trailer with the blower (they had the same part number), but still nothing on any of the fan speeds.

Mine quit a little while ago. Try tapping the bottom of the motor while it's turned on. This worked on mine. I finally got tired of tapping it and bought a new motor at O'reilly's. The hub of the fan blade broke trying to get it off so a little Super Glue and the spring clamp are still holding it together. The new motor makes noise unless it's on high (probably just can't hear it!). I don't know how long this one will last!

Solved the problem at least temporarily by tapping on the motor while on as suggested. Thanks.
