Working on a new to me '88 crew cab. Cleaning up the interior, wiring, weatherstriping etc...

The door locks don't work either lock or unlock. I tested and do have power to each switch's orange/black wire. I swapped out for know good lock switches from my other truck. Still don't work. The rear door locks are very hard to pull up, im wondering if the actuators are stuck to a point that the motors cant move them? Could a locked up actuator lock all of them?
