I have a 2006 DTS that currently has both front turn signals, both front cornering lamps, both fog lamps, and both high beams out. The low beams, rear and side mirror turn signals, and running lights still work fine. All of the lights on the dash (fog and high beam) display properly with the exception of the rapid turn signal flash. It appears that all of the bulbs are good, and I couldn't locate a bad fuse in either the front or rear fuse block. Do all of these items share a common ground?? If so, where is it located? Any help would be greatly appreciated!

It turned out that one of the three the wiring harnesses under the fuse box had come loose. It was the one closest to the windshield. I tightened the bolt on the top side of the fuse box and I was good to go!

This thread saved my bacon!
Same symptoms and tightening the bolts fixed it.
I can only imagine what the dealer would have charged me, that and just being without my car.

Thanks! Austijohn!
