Rear windshield wiper motor replacement

The rear windshield wiper on my car has stopped working - no fluid, no wiper movement, no nothing. The front wipers work fine - yes, fluid and yes wipers move. The dealer is telling me the problem is with the rear washer motor - conked/burned out - which causes the rear system to shut down. Can you verify does this car have a separate washer motor for the rear? This is not the same as the wiper motor, according to the dealer.
