Be careful spraying cleaner inside the case of the motor. This will wash out 
any grease that is left in the bearing causing earlier failure. The proper 
way to repair them is to take them apart and replace the brushes, clean them 
and re grease the bearings with the proper grease. WD40 or wheel bearing 
won't work. It has to be a High and low temp light grease that will stay in 
the bearing.

I have the same problem with my fans. If I drive thru standing water, 
it will splash up and gum up the brushes inside. A fix that will work 
is electric motor cleaner. Shove the little straw inside the drain 
hole on the bottom of the casing, and spray away. Just make sure that 
you wear protective eyewear when doing this.
