Every once in awhile either my left or right blinker will get randomly faster.

Then it goes away in a week.

It's really annoying, and I know none of the signals are out because the luights blinks fast in the reflections of other cars and in the garage when I tested it.

It's never both at the same time, it's either left or right. Hasn't come up with the caution lights yet however.

However, I want the issue solved or something.

 

Try to take out the bulbs from the corner light headlamps, and inspect the sockets for each of the bulbs. They could be slightly dirty, or the bulbs might have an inconsistent connection with the sockets. Some contact cleaner (from Radio Shack) will clean up the sockets.

 

Wow both of them are doing it. I heard of them doing that if they are going to burn out, but both of them going to burn out at the same time. That would be something. I would do what lexusk8 said. Did you just buy the car? If so then maybe the person who put them in did not put them in tight enough or something.

 

Not both signals at the same time. It was the right one for a few days, then they were fine for a week, then the left one for a day and a half and now it's fine.

I'll be popping out the bulbs and cleaning the contacts, as well as plugging them in tighter, if possible.
