Just bought a 2000 SR5 Sport and I have an issue with the power door locks. Both remotes lock and unlock the front door and all others with the second push but both interior door lock buttons do not lock or unlock any door. I have taken the drivers door switch out and all wiring, plugs and the switch look fine and all the windows work as well. I find it hard to believe that both interior door switches would go out on a car but I supose it is possible. This is something that I would like to fix myself without needing to take it to the dealer. Any help is appreciated!
