Check for corrosion on the connector or attached wire.
You need to remove the head light, which is rather simple, and reach through the opening from the head light to replace the light bulb for the blinker.
the light burnt out and you need a new one?
Check bulb if other side front is working.
Your light has gone out or a bad fuse
Bad earth connection at light cluster?
An L.E.D blinker is an L.E.D light that blinks on and off.
Replace the tail light bulb from inside the trunk after pulling back the carpet. This should probably fix your blinker too.
How about a malfunctioning brake light switch
Maybe your blinker realay is out.
when you flip your blinker on, a relay in the circuit is activated which turns the light on and off. also, the front blinker and rear blinker usually alternate in turning off and on, so when the back is on, the front will be off, and reverse.. that's why when a bulb is out, the clicking sound in the vehicle goes faster than when both are in working order.
go to napa or auto zone. tell them you need a rear bulb. they will ask what kind of vehicle you have. enter it into system. system tells them what item is instock for it. then test it.
check your relay to the blinker. its wat makes it go on and off
