Not sure. When you turn the signal switch either way. Right and left signal lights Both at the same time come on on the dash, same thing happens when you put on the brake. Check all the bulbs. Front signals come on ok. Was using the emergency flasher yesterday for about 15 munutes. Parked it and got cought in heavy rain. It started acting up when I started it up after that. Acts like the Emergency switch is on all the time but It turns off.
