Basically whys it not working and what would cause it from what I gather... Plus Ive had this problem aswell
open the hatch you will see a flex pipe that s bends from the cars body to the door pull the pipe down carefully and inspect the wires... they are NOTORIOUS for cracking and like mine breaking... to put the tube back on remove the plastic clip carefully not to break the pressure tabs slide the end of the boot back on (boot is the end of the flex pipe) and clip it back into place... right now I have soldered my third light wire back together and temporarily taped every wire in there (every wire was severely cracked and degraded)
and this if im not correct may be a TSB/Recall for your version car
Sadly its not for mine and I have to foot the replacement harness cost
mines 1 year newer and when the third light stopped working and we hit the brakes the rear window wiper would activate ( wire broke and was shorting against another cracked wire which was the wiper...
