I took my actuators out because they didn't work and it was a PITA to lock/unlock the doors with they connected to the PWDL actuator.....one of these days I'll get back to it....:doh0715:
You may want to try this first, spray some lubricant on the PWDL actuator so it's rod can move, they're supposed to twirl up & down whn activating the open/close button but from moisture, water over time they can rust or it's fubar but can be replaced. IIRC the last time I checked they cost around $90.00 each so you may want to shop around on the internet and see if you can get a better price otherwise all you have to do is disconnect the "door lock rod" going don to the actautor, there are "clips" that sort of swivel on the rod so just pop it off.
If not then you have a problem with the "latch" inside that closes on the "door striker bolt" part # 38420 $7.99 and "door striker bushing" part # 38424 $3.99 which is the anti-rattle device both mfg'd by Doorman to be found in the Help section of any auto store.
Using a # T-50 Torx socket door striker bolts are adjustable and removable to replace the anti-rattle bushing/s, over time the bushings can crack and go away so to replace it use some lubribcant to help slide the bushing on the bolt shaft.
Last, you may need to spray lubricant in the door latch from inside to help free that up from possible corrosion OR something is broken in the latch preventing it from "releasing" from the door striker bolt in order to open the door ......try and figure a way to trigger the latch from inside the door.
I don't know if you can loosen the door latch from inside bacause it has large phillips head screws on the outside......that you can't get to now because the door won't open.
Good Luck ~ :thumbup
