a shorted or bad bulb
bad ground in socket
A mis-wiring or short circuit somewhere between the controls, fusebox and lights.
Replace the turn signal flasher relay.
If the right one works,it might be a bad bulb or a bad ground.
Sounds like you need a new flasher.
That sounds like a grounding problem, probably near the right side lights. It might be a rusty or disconnected ground wire.
POSSIBLY A BADGROUND
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
It has been my experience that a rapid turn signal indicates there is a burnt-out signal light bulb (either front or rear) on the side of the rapid blinking signal. If the right signal is blinking rapidly, the problem is in the signal lights for the right side (front or rear) of the vehicle. Turn the rapid signal on and step out of the vehicle to find which bulb is not lighting.
Sounds like the turn signal indicator lights.Sounds like the turn signal indicator lights.
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.
I would replace the turn signal switch.
Bad turn signal flasher.
You have a failed bulb on the right 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.
I was wondering is there a fuse diagram for the 2003 Ford Explorer XLT? What causes the left and right signal lights to not work on the 2003 Ford Explorer XLT? Can the side mirrors on the 2003 Ford Explorer XLT?
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.
Normal cause is failed bulb.
sounds like you have a bad turn signal flasher One bulb is bad. The right rear turn signal bulb is burned out
You have a ground issue. More than likely it is not grounded properly. These can be very, very, hard to find. Been there and done that. I can only tell you to check all ground connections at the taillight assembly.
Sounds like you simply have A burned out bulb, Turn the signal on and look at all the lights to see if any are burned out. Could be A marker light if its in the turn signal circuit.
Sounds like you have a short in your wiring harness for your rear lights. As for your dash turn signal light, your dummy light is just acting up. You probably need a new wiring harness for your rear lights.
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.
It could be a faulty ground wire.
