Keith Browning Posted July 8, 2005 Share Posted July 8, 2005 I have been noticing an increase of multifunction switch failures in Super Duties that don't appear on the surface to be the switch itself. Of course I am talking about symptoms that don't make you immediately think "multifunction switch." Inoperative brake lights and buzzing in the dash from the flasher relay are the two most common complaints. I saw another today: just driving down the road and buzz buzz click buzz! Step on the brake and it goes away! If you come across this I recommend that you play with the hazard switch. Doing so will definitely cause a change like lights start working or the buzzing gets louder - both with the hazard SW. in the off position. I guess dirt is getting in there an messing up the contacts. Lust a little heads-up ! Quote Link to comment Share on other sites More sharing options...
