Assuming you have checked all of the bulbs, sockets and wiring, the signal flasher could be weak or the signal switch is bad.
Its the turning signal/flasher module, left side of dash behind the fuse box. Its a dealer part only about 98.00
to the left, right, or under the steering wheel.
the left turn signal light on my ridgeline does not work but the right side works
Sounds like a blown bulb somewhere on the righthand signal side.
If you mean that the arrow inside the dash turns on and stays on then your problem is one of the left side turn signal bulbs. Test by turning on your four way (hazard) lights and observing all lights. The one that does not flash is the bulb that needs replacing.
The fuse for hazard and signal lights on the Nissan Serena is in the fuse box, bottom row. The flasher fuse for hazard and signal lights is located in the dash just to the left of the radio.
The turn signal flasher is next to the fuse panel at the lower left of the steering column. The hazard flasher is located to the right of the steering column.
i have conected the black and red wire to the brake and it works (the brake light that is) and i conected the blue and white to the signal lights each wire being left and right signal and it all works. but when i brake all of the light lights up the red bar for the brake and the orage bars left and right when i signal left or right whiles braking the signal works but the other signal light sticks on with the brake light. so if any one as any idears please let me know thanks
Check the left turn signal bulb. It is probably burnt out.
Depending on what type of vehicle it is, it could be the combination flasher relay. 2000 Dodge Caravan, same problem. Replaced DRL/Flasher Relay, problem fixed. Was an expensive dealer only relay...
It means that a light bulb is out on the side where the light solid (not blinking) it could be in the front or rear of the vehicle.
Start with checking the bulb and socket then wiring. If it is the same light for the direction signal and that works OK then it's the hazard switch or relay.
