Ok, so after I finished replacing the rear brake light on our 02 Passat, and the rear blinker on that side stopped working. The bulb looked fine, but I replaced it anyway. Still not working. The front and fender blinker are working, but not the rear, so its blinking really fast on the other two. If it was the flasher, wouldn't they all stop working?

 

Never mind, I got it working. The bulb was fine. I turns out the blinker, which has its own seperate socket from the brake/reverse light block, wasn't making a connection with the block. And, the other light I replaced was the reverse light, I thought it was the blinker. I feel a little dumb
