Mine too, i think it may be,the lock itself,as i have had other troubles with it,mostly locking the door and not releasing . It seams to be a problem with the internal door cable not allowing the opening latch to return properly. I'm sure it will have an internal spring that has broke. Have read on other posts that water under the drivers carpet can play havoc with some of the wires to the locking, water normaly comes from heater matrix. with mine when it starts doing its lock / unlock thing it never locks the nsf door,don't know why? it don't do it all the time some times daily and then nothing for weeks, try a spray of wd 40 on lock mech and see if that helps. sorry can't be more help.
