A car that won't move when in reverse could indicate a problem with the transmission. It could also indicate a problem in the gear selector.
Could be blubs burntout,fuse blown or a bad relay switch. If that's not problem. Then could be switch on the shifter or on transmission depends on year of car. when you shift to reverse it should trigger switch for backup lights.Hope this helps.
first check fuses,then bulbs,then reverse switch on trans mission,it might need replacing,its screw into your transmission.
Very possible ... best to check the wiring with a voltmeter checking for +12vdc.
could be the neutral saftey switch .
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.
Check the fuses first then check the bulbs.
Did you check the reverse light switch on the shifter ? Could be bad or not contact.
Could be switch on gearbox, wiring or bulb.
There is a backup switch in the gearbox. When you shift into reverse, the gear box switch contacts the switch and lights the white reverse lights. If you find that the reverse lights don't work it could be that the switch is not being triggered by the mechanism inside the gearbox. This is providing that everything else is working; wiring,bulbs,etc.
Could be the brake light switch or fuse.
Could be a linkage problem..
