when i first got the hatch, the turn signals didn't work correctly. the corner lights didn't work at all. the relay kinda worked. it would click fast one way, and normal the other way. usually when it clicks fast, it means you have a blown bulb. i replaced all the bulbs and replaced the relay yesterday. the corner lights work now, but it still flashes fast when i turn left, and normal when i turn right. what else is there to look at? i looked at the wiring, and everything is in tact and grounded like it should be. (i used a test light and lead wire). all the lights work, but its annoying to listen to it, lol. any suggestions?

 

short to ground, bumper bulb may be dead, bu t check wiring, take a DMM and check for continuity from the power for the turn signals to the body ground. if there is, then you got a short.

 

the fast flashing can also mean one of the bulbs is on its way out, so it may be one that works that you havent changed yet.
