Did you check the fuse diagrams in the owners manual to see if there is a separate fuse for the left and the right doors? On sedans, IIRC, there is a separate fuse for the front and for the rear doors. Then your next question is if there is a control module in that door that takes the commands and passes them to the appropriate motors. The control module may be defective or the power wire to it may have broken where it flexes passing from the A-pillar into the front of the door, usually through a rubber protector sleeve.
To avoid wasting money, you're gonna need to do some detective work with an electrical meter after checking for fuses.
