Hi!

I just got my diamond white pearl '08 navi TL (with 50k miles) last Saturday. Yesterday, I went to a local shop to have my windows tinted. On my way home, I noticed that my doors locked and unlocked by themself many times during maybe 20 seconds. I noticed later that my passenger side door lock knob doesn't work anymore. I guess some water went into the door and in the knob. I disassembled the door and swapped both front doors switches and it looks like the knob works on driver side. So, it looks like it's a broken wire or a bad MICU. On a side note, when I plug the knob on the harness, the doors unlock (without pressing a button). It doesn't act this way on the driver side. Stealership is out of the question. Any idea how I could troubleshoot the MICU ? Is there any kind of protection (like a hidden fuse) ? Any relevant idea ?

Thank you !!!

Will
