What was the solution?
I have a 2012 Silverado - 3 days ago the parking lights wouldn't go out - pulled the relay they are off. Tried other relays and same issue - won't go out. Now today my instrument panel lighting will not go out. A remote start was installed 3 months ago so I don't think that would be the issue. Everything else is factory. The last couple of years the radio lights intermittently don't work - the clock portion will go out and/or the stations along the bottom are not lit.
