Replace the turn signal flasher relay.
You may have a "ground loop" problem on the left turn signal. Check the ground wire at the front and rear signal bulbs.
was jeep in accident and repaired? sounds like crossed or shorted wires
I suggest that you check in back by the trunk and back lights the there may be a short or the wires are lose
More than likely the Flasher Relay is bad. If the bulbs are lit but will not flash it is definitely the Relay. This can also indicate a bad bulb on one of the lights on the side that does not flash.
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.
You need to locate your flasher, usually near your fuse box; is sounds like your flasher is burnt out for that side.
When it flashes fast it means you have a burned out bulb omn that side. Check all you lights and you'll find the one that's burned out.
You have to replace front and rear bulbs.
Bad turn signal flasher.
Turn on the RIGHT turn signal then get out of the vehicle and see which lights are flashing. Count the number of bulbs that are flashing on the back of the vehicle and on the front. Then turn on the LEFT turn signal and check again. Usually a rapid turn signal indicates that one or more bulb has failed.
It turns out the problem was that a couple of bulbs on the left side were burned out (front left turn signal, one of the rear turn signal/brake light bulbs.) After replacing the rear bulbs, the signal would work, albeit slowly. Once I pulled the front left turn bulb (with the intent of replacing it the next day), the turn signal light went steady-on regardless even without moving the signal indicator arm. That problem also went away when the remaining bad bulb was replaced.
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.
Short to power in the brake light circuit. Most likely, the fault is in the switch itself.
If the turn signal lights come on but do not flash, then Flasher Relay is defective, replace it. If they flash but one does not work the bulb is bad, replace it. Flasher Relay is located below left hand side of steering column.
It looks like your left front one is burnt out. When there is not enough current flow the good light will not flash.
Turn left indicator signal flashes rapidly when I use indicator, bulbs ok, no lights working
Check the left turn signal bulb. It is probably burnt out.
Check ground circuit Check bulbs they are duble filamented one may be burned out Seems to me there is a wire crossed at the harness. I think the vehicle left turn signal wire is hooked up to the trailer tail lights wire. Usually there are four wires at the trailer harness, yellow, green, white, and brown, The brown wire is usually the tail lights and side marker lights, the white wire is ground, the yellow and green go to the left and right signal lights.
Its the turning signal/flasher module, left side of dash behind the fuse box. Its a dealer part only about 98.00
Normal cause is failed bulb.
light is burned out
if your signal is faster than normal then you need a new bulb
1989 silverado left turn signal set applying brakes causes the left turn signal to dim and the two right rear tail light bulbs to alternate brightly? Further problem occurs to same truck - in Park and brakes not applied -- if head lights are on turn signal flash slows right down almost to a stop and becomes very dim
flasher will not flash when circuit is open or shorted replace left front turn signal bulb
