Problem with turn signals
I have a 06 gt and my blinker is blinking fast for no reason. I know I checked all the lights and they all work but here's my problem. I have sequential tailights so I thought maybe there's a problem with them, but when I put the stock harness back on only the middle light would light up. So I replaced the 2 bulbs that didn't flash. Still doesn't work. But with the sequential harness in they all light up. Has anyone experienced this?!?
