[Flying Hamster]

If it has been used on rough roads, the clusters go dead.
I'm on my third cluster in my 2006, and it goes out and resumes working on a regular basis. 140k miles, only real problem with the truck.
Does any part work? will it light check lights if you turn on the key but don't start the engine?
(If you smack the dash does it come back on? Mine does... for a little while.)
