Here's the background, while driving last week my turn signals stopped working. The dashboard indicators showed that they were not working, and a visual inspection outside the vehicle confirmed it. Midway through the trip, I checked the fuse. The fuse had not blown. I swapped it with another fuse of the same type (I think it was for the fog lights). The signals still did not function. I continued on my trip - reaching my destination about 250 miles away.
After letting the car sit for about 90 minutes, I hopped back in to continue my trip. At that point, my turn signals worked again. The turn signals continued to work for the rest of the weekend, another 350 miles or so, and are still working.
What happened? Should I take this in to the dealership? What should I suggest that they look for?
