If the fuses and bulbs are all good, replace the flasher. there might be two. If that doesn't do it then it's probably the turn signal switch. Check for voltage at the wiring harness coming into the steering column with a test light. You should have a steady light with the key on. turn on the signal for one side. You should have a wire that will blink the test light. If you do then you have a bad connection somewhere close. if you don't then you have an open circuit from the fuse box. Hope this helps.
Check fuse,bulbs, flasher
Check the fuses and the bulbs.
I also own a Nissan Pulsar Q hatchback with the same problem. One reverse light is orange, the other is white. The dealership when attempting to fix this problem assumed I had two white reverse lights so my car short circuited. I have been told for the orange light to work I have to turn on the headlights, (sounds a bit dodgy) Not sure if it makes sense, but I hope it helps.
Faulty light bulbs, damaged engine.
Check fuse, bulbs, and flasher relay.
replace the flasher(underneath driver side dash panel)
check your bulbs some bulbs have two filament on them one may be out and the other working.
It could be the turn signal bulbs, some vehicles use separate bulbs for the hazard and turn signals. It could also be a bad switch or wires for the turn signals.
If the turn signals are not working properly on a 2002 Chevy Venture and the fuses seem to be alright, check for burned out bulbs in the turn signals. Also, check to make sure the turn signal flasher is working properly.
Check for burnt out bulbs and could be a bad flasher as well.
First have you replaced the bulbs in it and there not working or do you need to know how to replace them
Check bulbs and flasher if all are out most likely flasher is bad Check bulbs and flasher if all are out most likely fuse or flasher is bad
