Had a quick look for that car on google, bit hard to make out from small pics, but. Looks like 2 screws and the plastic cover/shield will come off, then get a much clearer view of the pinion.
From there, if the shaft sticks out beyond the pinion I would stick my finger on it and run the motor, feel it if spins or not. Or small dot on the end of the shaft with a felt tip, see if you can see it move.
