Don't even bother calling the dealer for "a" motor. The "unit" is sold as a set and runs upwards of $400. 00. No, you can't buy just the motor(s) and when I checked the after market, it was dealer only. So, you can try to take the motors apart clean them up and lube all the parts like I did and waste an afternoon. Or, as I did after wasting the afternoon, adjust the rear butt part of the seat where you like it and leave the motor disconnected electrically. If you have both front and rear height adjustments screwed up the best bet is a salvage yard. Remember the dealer will tell you the "unit" they want you to buy is not serviceable - I had mine all apart including the motor to clean the brushes etc. it is serviceable. Salvage yard is your best bet. Good luck.
