Last week my turn signals quit working, but only for a short time. Since then they have quit working a couple times, but they always come back. Today, I went to hit the left turn signal and the right one came on. I tried the right one, and the right one came on. The only thing I can figure is the solenoid type thing that controls the blinkers, but I can't find it. I didn't see it listed on the lid of the fuse box. Any ideas?
