Door lock Actuator question

ok so i replaced my worn out door lock actuator with one that i grabbed from the pull a part the other day. after installing the new to me one when i go to lock and unlock the doors via the fab or the switch i hear a whirling sound but no action on the cable to lock and unlock the door and ideas of what this means possibly grabbed a bad one maybe?

Thanks in advance

Did you clean and lube the actuator that you got from the jy? The "whirling sound" might be the power lock trying to work, but meeting too much resistance.

When I did mine, I cleaned it up like new with WD40 and Q-Tips until I could work the lock smoothly by hand. When I installed it, it only needed a little position adjustment and it worked great. Just for the heck of it, I cleaned up my old one and it works too...

lol, I think you read my mind because this exact same thing happened to me. I havent cleaned anything yet on mine. I can hear the actuator trying to work, so I know that its getting power, but it sounds like a gear whining, and nothing happens.

you can take the screws off the side and the plate will come off and you clean under there. you have to be careful though because theres some springs in that will try to shoot out

I did not open mine. I just sprayed WD40 in every hole and stuck Q-Tips in and out until the came out fairly clean (repeat several times). I am sure that it could be cleaned more thoroughly if you opened it, but I was afraid that I wouldn't be able to get it back together. It definitely worked much more smoothly after cleaning.

I had to cut the plastic motor case on the actuator off of mine with a Dremmel. The two plastic gears on the electric motor(one on top of the other)were spinning but not engaging the lock. I cut two very thin pieces from an allen wrench, drilled holes in the gears, and mated them together with the two pieces so that when it activated the gears turned together. I RTV'd the plastic case back on the actuator and reassembled with fresh grease. Been working for almost two years now.
