Sorry, can't help with the original question as my solution to the same condition as you describe was a new actuator, replaced under warranty.

Your microswitch theory is worth pursuing, but only if an open door responds to a pressed lock button by actually locking and unlocking (as opposed to simply not responding). I feel like it's the latter, but I can't check right now as my wife has the S80.

Good luck with it..

 

If I open the door it locks and then pops right back up. 99% sure its the microswitch. Just not sure how to go about disabling just that for the time being.

 

Obvious, but have you checked if there is anything blocking any of the other doors from closing all the way?

 

Yes i have. Its the drivers door 100%.

 

I had the EXACT same problem on my 2009 Volvo s80 3.2 It turned out it was the wire that had broke that travels between the body of the car and the door.
This is so because SOMEONE at VOLVO Decided it would be a good idea to to attach a zip-tie around the wiring harness right where it flexes this in return,
Causes the insulation around the wire to wear down eventually wearing its way through the wire causing the circuit to be compromised.

My Repair:
I ended up removing the door this was really just for ease of access to the harness.
I ended up putting a simple wire crimp between the two broken wires putting tape around the crimp and that's it.
(you most likely could solder in a wire to bring the two together.)
I put the door back on.
And verified my repair.

and I have a new used latch in the door that i didn't need, Not part of the repair lol..

Hope this helps - Sam

where is the wire located im having the same issues

 

Thanks for the reply. Do you remember what color wire it was? Thanks

 

I believe it was a purple wire with orange stripe but its been over a year since i did the repair so not sure.

Edit: ill look on the VIDA wiring diagram in a few minutes and get back to you.

 

Thank you! I’m going to remove the door this weekend and have a peek. Appreciate it!

 

Had some time today. Removed the door and found 2 wires that had the insulation coming off. I fixed that. Still have the same problem. I have no problem buying the actuator but want to try and fool the system before I spend $200 on something that doesnt work.

 

Anyone? I cant lock my doors. Driving me nuts!

 

Took out window regulator, lock assembly etc. Found a broken wire in the loom to the lock assembly! All is good now! Thanks for everyones help.

 

Nice work... will keep that knowledge tucked away just in case

 

I had the same issue dome light and center lock wasnt working. I tried all the solution including cem service. Program reset but all those solutions didnt worked for me. I had the issue for 7 months.

Then i found the exact issue location by mistake. I had to replace my boot . Then suddenly everything worked perfectly. So the issue is from the boot lid sensor.

Thank you members i got so many solutions from this threads. And this is a chace to serve you back.

 

fixed it. I had the same issue for long time. I tried all the treads about this fault but there wasnt any solution or fix . But then I had to replace the boot. Then it fixed the issue the dome light not poering center lock not workingand doorlight keep on. But then some how i replaced the player. While doing that problem came back then i noticed exact issue is with the a/c control panel socket. Then i removed and plugged it several times. It fixed the issue. Solution 1 check a/c control panel sockets below the player. Solution 2 check the boot lid sensor . Thank you all. Love from . Sri Lanka.
