Lights problems S40 2004.5

Hi everybody!
I searched but haven't found the exact same problem.
I just bought a 2004.5 Volvo S40 2.4i.
All lights were working fine, but now parking/side lights (2 bulbs in each headlight assembly) and tail lights doesn't work anymore. License plate light is out too. HID low beam and high beam work, turn signals work, front and rear fog lights work... Brake lights work, although the right one and the third one seem to turn off right after turning on (like a flash). Left one works fine.

I checked the fused related to lights, but they seem fine. So do the bulbs (would be surprising that more than 7 of them blow out at the same time anyway)
Do you think it can be the light switch? CEM?
Thank you for your help...

Oh my...that's a good one. I might try disconnecting the battery (key out) and pushing the brake pedal and then reconnecting to see if anything resets. Otherwise, it sounds like it could be shorting of wires somewhere...hard to say.
