i just got a 95 ls and the lock on the driver's door doesnt work. the key wont turn and the manual lock button on the inside wont work( i opened it up and the rod just bends when pushed). the power works fine. so to get in i have to unlock from the passenger's side and then i can open driver's side from the outside. i sprayed some wd in there but i just cant get good enough access to the problem. is there a way to fix this myself? thanks
