mac, could be that , after maybe eliminating fuses, power "actuators" in either/both doors not be "right". If a newly bought vehicle - I would get the trim off the easier of two doors , to "jump-test" it's actuator , and NOW more importantly you may
FULLY inspect the door's INSIDES to SEE IF CAR WAS in a FLOOD (damage) AREA and had been under water ?? Do this to other door too.Gotta know - you know.

Not to be a wiseguy ,but Let's see , Katrina was - when !!!!!
