Default Re: 09 YDRE Won’t Move After Removing Motor

Take the motor apart further, inspect terminals (that you were suspicious of), and wiggle/move the 4 carbon brushes to see that they aren't "hung up" at all. This will give you a chance to check their length too. Any nasty grooves & funny rainbow colors on the commutator are a bad sign. Commutator is the copper bars the brushes press up against. This is surely a motor issue of some sorts.
