parking brake light on on 2003 Chevrolet Avalanche 1500

parking brake light stays on after release of brake pedal and driven, the chiming was non stop. don't see any leaks of fluid and brakes still feel normal been like this for only a couple of days

Check the park brake warning switch its about $5 plus shipping at or you can locate a shop here
thanks, is that the harness by the park brake pedal?
Purchase the switch at the dealer or so you know what your looking for before taking anything apart
