How do I replace my electric door actuator? on 1992 Chevrolet 1500 Pickup

I took the door panel off and there does not seem to be a hole to get into replace the actuator motor? Any ideas??

Are you talking about the lock actuator or window motor?
Lock actuator
If there is a plastic covering remove it carefully so it can be reused, you then have to reach thru the existing holes and be able to work in confined space. Look for the old part and see how it attaches and what is hooked to it. It will have linkages attached with clips, be careful not to break them or will have to go get more. If you can put a tube or stick light in the bottom of door to help illuminate. You can look at the new part to help see where it all attaches.
