So I have a 1996 silverado 1500 z71. When I bought it there was no key for the door locks. So I got a locksmith to cut me two keys and now I have keys for the locks but when I tried to click the lock and unlock switches, nothing happens. I was guessing since the guy who I bought it from lost the keys he pulled a fuse or disconnected the locks so he didn’t accidentally lock himself out. I pulled the switches and they are plugged in. I checked the fuse in the dash #13 and I took #15 fuse out and tried to put in #13 spot to see if the locks work and nothing. Could the actual door lock actuators be bad? Both sides do not work
