Sometimes when I put my E-brake on the daytime lights don't shut off and the red "BRAKE"dash light does not come on . BUT ..... if I go out to the car a few hours later start the car the lights are off and the red dash "BRAKE" light is on. what could this be ? a switch at the E-brake handle or something else? also I think my accumulator is starting to go could this be part of the problem? THANKS.
