Hi im new here, and I know this topic is probably pretty redundant so pardon my ignorance on the matter but Im having trouble with my door locks (2003 G35 Coupe 140,000 miles). They refuse to lock whether I do it from the key fob, automated door switch, manual door swich, and even the key hole on the driver side door (damn thing wont even move nomatter which direction) and the is the problem with both doors too. Its seems like power is being delivered since I can here a sound in the door with input, I was wondering whether or not its an actuator issue so thatI can by a kit to fix it. Also note, not sure if it means anything but when I got the car (from auction) the airbag light was on and still comes on and never turns off. Any help would be much appreciated!
