I've tried searching multiple ways and couldn't find an answer.
My right front turn signal went out so I replaced the bulb and everything seemed fine until this morning - it sat over the weekend. I started it up and noticed the right turn signal light on the dashboard was steady on. When I moved the turn signal lever to on it did that fast blinking so I figured something was up but it was 5:30am and I had to get to the van pool to get to work. On the way there, about 3 miles into the drive, at about 50mpg, I started hearing this alarm coming out of the dashboard. As I slowed down for a traffic light, the alarm stopped. It stayed off for about 2 miles at which point I was going about 55 mph. I pulled into the parking lot and as I slowed down, it stopped again. This whole time the turn signal was steady on.
