My first guess would be that the ICU is failing. This is a small board under the fuse panel that controls many of the dash functions. There were ICUs with capacitors that go bad causing the board to malfunction. Repair/replace is relatively easy, however the bad news is, it is fairly hard to get out because you have to more or less remove the fuse panel to get to it (it is on the fuse panel on the BACK side), which means disconnecting many of the cables that go to it.

Another possibility is that you have a grounding issue somewhere in one of your front lighting wire harnesses.
