if i disconnect the batery, it temporarily fixes the promblem
my brake lights randomly stick on, draining the battery. on 2001 Cadillac Eldorado
Have replaced several, they do stick. Replace it before you can't get the shifter out of park.
CK BRAKE LIGHT SWITCH IT'S MOST LIKELY STICKING.TRY WD40 OR REPL THEY ARE CHEAP
