Start narrowing it down, First unplug the rear tail light harness back by tail light and retry, then, unplug complete hood harness and retry. Then unplug turnsignal switch.  There was a recall on the fuse panel by the clutch pedal on some trucks for water getting in to relays and fuses

Okay, is this assuming there is a short somewhere?

So bought a 5 year old CXU613 last week with 267K miles. The truck passed a PPI, a few issues were identified but no deal breakers. 

Last night on it's second day of service my driver called to say he lost head lights, dash lights and marker light simultaneously. At the same time the high beams came on. After the truck was parked and sat for a few minutes, we started it up and turned on the lights. The same thing happened after about a minute along with a lot of clicking from under the steering column.

Has anyone ever seen this happen before?

I'm getting ready to buy a 2011 CXU613. My shop noticed this during a pre purchase inspection.  After reading this and other threads elsewhere, I'm a little less concerned. Not 100% certain on what to ask of the dealer before pulling the trigger.
