Check bulbs Check sockets for corrosion Check sockets for power and ground Check fuse for stop lights Check fuse for parking/tail lights
you need to buy a signal lights relay
There is a short in the signal light circuit.
Probably Flasher
the carbaretta could have blown mate
There should be six signal lights on the mystique, two front, to rear, and two sidemarker lights.
Check the signal light fuse, the signal light relay, and the signal light switcher.
It's the turn signal switch which is the culprit.
blown bulb due to short circuit, faulty ground, or broken wire
Try checking & replacing turn signal flasher, which is usually located underdash by your left knee if your sitting in the drivers seat. Good Luck...
if turn signals are working , and brake lights not working, i would replace the stop light switch on the brake pedal
change the flasher
check the fuse
