Undo the four 13mm nuts and two 13mm bolts holding the two brackets.
Remove the running board from the vehicle.

motor end cover - two screws.
Take care not to lose any shims.
Spin the armature until it stops.
Then you can see the wedge bolt.
Remove the wedge bolt.
Knock out aluminium wedge from the back.
Note the orientation of the wedge, for re-assembly.
Also note the position of the boards.
Stand on the board and work the hinges back and forth, whilst liberally spaying all moving parts with penetrating lubricant, until moving freely.
If step 10 improves the operation of the hinges, possibly your motor
is OK, and you can re-assemble your board and re-test.
Otherwise, you need to replace the motor.
Choose from the list on the home page.
Re-assembly is simply the above procedure in reverse.
Ensure that the running board is in the same position as when you started.
Otherwise you may end up with the boards working in reverse - i.e. retracting instead of deploying, and deploying instead of retracting.
RETRACTING INSTEAD OF DEPLOYING?
(Probably you moved the board's position before refitting.)
To rectify, unplug the electrical connector and open the door, then refit before closing the door.
FLAT ON WRONG SIDE OF SHAFT?
To rectify, remove the cover and turn the armature by hand
