Hey guys! So since I'm sure most of you know I know absolutely nothing about cars, trucks, jeeps, etc., I figured I'd ask y'all about a minor problem I'm having with my truck. It won't lock! When I press the lock button, sometimes the driver's side will lock and sometimes it won't and the passenger side never will. My friend told me to put WD-40 on the locks and my stepdad said all you have to do is take it apart and clean it. And I would help him do that but he's in the hospital so he can't and I would like to get it over with. So any answers that don't require taking my doors apart would be greatly appreciated.
