the blinker relay is probably bad
They dont work. The bulbs are the most problems. Fix it!
Blown fuse, or defective flasher relay if all the bulbs are good.
blowen fuse oh and check the bulbs I have the same problem with mine, I checked the bulbs and checked the fuses and they still dont work
Bulbs may be blown.
Check fuses Might be a bad ignition switch
check your fuses and relays
Defective reverse light switch.
Check the bulbs & fuses first. Then if o/k start looking for electrical problems such as switch, wiring & sockets
Brake pedal switch, wiring, bulbs, bad trailer harness (if there), fuses...
I am currently having the same problem you are having check the fuse to see if it is blown the blinkers and brake lights are on the same fuse my system has a short in it somewhere and is popping the fuses I am in the process of running new wires since the wonderful people at Chevy ran all the wires thru the frame and you can't access them
Check for a loose ground or loose bulbs.
For the PS2 version there is not any indicators (blinkers). I dont think there any on there other consoles ether, but there is a horn and headlights.
