I was having a problem with my driver side door ever since i bought the cl55. Nothing would wouk on the door panel unless i had the door closed_no window power seat control, auto shut window, nada. Very frustrating .
I started doing alot of reading and found that it was most likely the wiring inside the door boot.
I pulled the door panel off but really there was no reason to.
Ended up finding the main 12v power wire into the door was broken in half inside the boot. I soldered it up and put it back together!
Easy fix, here's some pics
Thanks
