I have the exact same problem.

Was the engine hot when this happened ?

This is supposed to happen. After so much time has elapsed using the AC, the blower comes on and cleans out the condensation on the inside of the system. Freaked me out, too, but I had read this in the manual so I figured out what it was. This is NOT a problem.

Mine is doing the same thing. I have taken it to the shop and the mechanic can't find anything wrong with it. When he resets the diagnostic, the car runs fine for a few days then it happens again. I'm thinking it is something due to the cold temps here in NW Iowa. It is obviously not a cold weather car!

yes it is in trunk, open back door and find out one pull knowb exactly back side of fuel lid door. just pull and door will open.

I have the exactly same issue. Did you solve yours?

Go to the Fuse Box at the end of the dash, pull the fuse for the SWM (Steering Wheel Module) re-install the fuse and the controls should work. There is software from Volvo to prevent this from happening. learn more at RepairPal.com

turn the key around and insert it ,when you turn it should work

i have a 2000 s60 2.0t and got the software update due to the recall. it apparently was some kind of safety measure when a fault of some kind occurred but it nearly got someone killed while overtaking and thats why the recall happened. sounds like the same issue but i could be wrong.
