prostar info center no longer readable and brake lights stay on

[BCODERRE]

Anybody had a problem with info center on prostar becoming unreadable? when I bought the truck 1.5 years ago with 250,000 miles on it, itwas abought 75% readable but now I can,t even see the milage. Also started having dead batteries. Found that when the key was turned off the brake lights would come on. Now they stay on all of the time. Unplugged the brake switch but that didn't shut them off. Found the relay for the trailer brake lights which did shut off the trailer brake lights but can't find a relay for the tractor brake lights. Any info would be appreciated. btw truck still only has 260,000 miles.
