W203 Door Lock Pogo Fix

Still have a glitch. The door operates, but the solenoid won't lock the door. Any thoughts?
(Figured it out. When I put the door together, I was testing without the door's interior, and the plastic latch piece that screws on. This kept the door pin thinking it was open, therefore the lock wouldn't operate.)
I took pics, and will write it up. Just need some time tomorrow.
FAWK!

Could you post the pics please? A write up would help too. I need to fix my driverside lock mechanism. Dealer wants $500 to fix a part that costs only $86. I'll try to fix this without them.

I'll also pm you my number in case you have questions.
If you need the pop rivet gun and the rivets, you are welcome to borrow mine.

Dealing with the dealership when you have a motor swap is kind of weird. Not sure if I trust them anymore with this kind of stuff.Don't worry too much about the rivet gun. I can probably get those from Home Depot or Harbor Freight for a few dollars. I just need helpful hints to get me going.
This problem with the door lock is common on the W203, ain't it?
None of our Japanese cars have this stupid problem.
You will need: Set of Spline screwdrivers, Flat screwdriver, Pop rivet gun, 3 small cable ties, Drill and 5 pop rivets.
1. Pull off the tweeter cover on top of door panel near front of window, no need to disconnect wire, just let it hang down.
2. Pull off SRS badge and remove the spline screw behind it.
3. remove the door latch plastic cover (1 screw)
4. At the bottom of the door pull handle next to the armrest there is an oblong slot, insert a flat screwdriver and prise the top half off, it is just clipped in. there are 2 spline screws behind it, remove them.
5. Using a plastic wedge of some sort or just by hand and starting at the lower part of the door latch, prise off the lower half of the door panel there are 6 or 7 plastic clips which hold it on, (I did this by hand and without breaking any but it may be worth purchasing a few just in case)
6. Lower the window and while pulling the panel slightly towards you, use your other hand to pull the panel upwards from the top starting at the front end, (this is quite tight, but it will come up)
7. panel is now off, pull the plug from the window switch and disconnect the cable from the door handle by opening the handle slightly and pulling up on the hook, the cable can then be removed from the door panel insert.
8. Drill out the 3 pop rivets holding the air bag and the 2 pop rivets holding the lower window strut. do not disconnect the airbag, let it hang down or tie it out of the way.
9. Remove the 3 screws holding the door latch and disconnect the wire from the panel near the front of the door. ( I actually cut the wire and pulled it through the loops to keep the original cable ties in place, when I replaced it I just used new cable ties to attach it back to the original location.)
10. You can now remove the locking mechanism by pulling it down and then towards the front by pushing back on the window strut.
Now do everything in revesre..

Where are you located? How many parts depts. did you talk to?
Help us to help you. Fill out your profile, tell us where you are.
Different dealers charge different prices. Some can get away with it, others can't.
If you have the door lock pogo, the only part to fix it will be the actuator module.

I have seen larger rivets. When you push that rivet through, i can't see how you would have drilled out a hole larger than 5/32.
So are you good at shapes or something? Universally, we have all had experienced the PIA when taking out the actuator.
What did you pay BTW?

Regarding the larger holes I used the wrong type of drill bits....made for wood I think. Needless to say I got a little impatient and started using different sized drill bits some that were probably bigger than 5/32....oopps.
I'll try the bigger rivets, that should do the job.
Thanks for the help!
It has been doing this for about 5 days now and seems to be having more and more trouble locking and unlocking each day.

The lock system may not work properly unless ALL devices in the door are connected properly to the controller.
During the door disassembly, the control wiring for the mirror was disconnected. When trying to test the new lock actuator, it would unlock properly (both by the dash button and the remote), but would not lock at all.
After several hours of troubleshooting, trying various things & doing lots of research, it was assumed that a trip to the dealer for diagnosis would be required.
After reassembling the door, it was tested one last time - and everything worked properly. After going step-by-step and reconstructing what had changed, it was found that disconnecting the power mirror connection to the controller in the front top side of the door, caused the power lock actuator to unlock-but-not-lock.
Go figure.
Hope this helps save someone a couple of hours of head scratching . . .
