Reverse lights not working.have check fuses and blubs

check your manual.. It may be a bulb that lights several fiberoptics to different gauges. It may seem like more than one blub making you think it is the whole circuit. If the fuse is not blown check for that one blub.

it is more than likely the switch.
On the 5 speed models it is screwed into the left side of the gearbox casing next to the driveshaft inner joint and on 6 speed models it is on top of the casing.
To test the switch, disconnect the wiring connector and use a multi-meter set to resistance function, select reverse gear and test for continuity across the switch terminals. If you dont have & meter you can make up a battery bell or light set.
If your test doesnt get a response from your chosen tester then the switch is faulty, sometimes it is just stuck and a tap on the switch will clear it, however if not sorry, new switch.
I hope this helps.

M/T on Tranny
A/T on Tranny,
if car is A/T its in the PRNLD switch, mounted to side of tranny.
it not only does reverse but sends your shift selections to the
ECU , so it can autoshift your transmission

the first check is , fuses
2nd ,is try one new bulb inserted, and all old bulbs in pocket
blubs can short.

could be a dirty socket not allowing good contact for the bulb. or you have a bad connection with one of the wires in the back of the socket.

The turn signals and brake lights use the same circuit and filament in the bulbs. The tail lights are on the other circuit which comes from the headlight switch.
Do you have power on the tail light fuse ?

check the brake switch on the brake pedal arm under the dash.

sounds like you could have a loose connection somewhere in the wiring at the parking lights.. check the blub housing to make sure all the tabs to hold the bulb are there,,, wiggle the wires a little and see if they are broken loose... also check the grounds... see if any are loose or broken..

Could be the reverse light switch itself, usually mounted on the gearbox with 2 wires coming from it. If you had a multimeter (set to resistance / ohms) you could check that the switch changes from open to closed by disconnecting the plug on those wires and putting the multimeter across the two terminals. The resistance will be very low with the gear lever in reverse, and very high/open circuit with it not in reverse. Also check that there is battery voltage to one of the terminals.

bulbs burned out or vehicle not recognizing reverse gear engaged at shifter-check wiring before condemning shifter assembly

Could be the mechanism inside the shifter that tells the car it's in reverse. Usually a little button of sorts.
