alright so this happened once before about 2 weeks ago but was fine the next time i went to the car. when i go and click my alarm remote to open the car the power lock would not close. it has something to do with the driver door(controls all other doors as they wil open and close freely manualy) i can hear the lock/unlock actuator trying to lock the car but nothing is happening. im assuming i have to take the door pannel off now and check it out. now im no mechanic(but an mechanicly inclined) so on a scale on 1-10 how hard or easy would it be to diagnose and fix? and after being put back on should i expect the same fitment?
