Okay so I has a 00 chevy silverado with manual locks an I found a pair of automatic locks from another truck that's a chevy Sierra 00 . If I take the out of that truck would I be able to put them in mine ? And also can I do that with the automatic windows to ?
If your year of truck came with electric locks as an option, the plug will be in the door. All you have to do is add the hardware, change out the door panels to fit the buttons.
You can buy add on kits from auto part stores to fit power door locks. You might be able to fit power windows and locks from the same model depends if they have all the same mounting bits to put them in the doors. You would also need the switches and controllers for the locks and windows and possibly the wiring loom. For the locks I would recommend one of the universe kits.
