Question for everyone here - I have a 2010 Toyota Sequoia, and the passenger side turn signal appears to be malfunctioning. I noticed when I used it while driving that the typical clicking sound was going much faster than normal. Once I was back in my driveway, I inspected everything and found that the turn signal bulb was burned out, so I replaced it.

Today, the damn thing is burned out again. When I inspected the bulb housing, I noticed that it appears to be scorched. I haven't compared it against its opposite number on the driver's side (which is working normally).

Has anyone dealt with this kind of issue? I'm taking it in tomorrow to the dealer for a diagnosis, which will run $80 unless I elect to have them repair the problem.

Get a new bulb housing.

I think this is what you need.

Thanks.

That looks like a simple plug-in component. Not being a car guy, can it really be that simple?

I did just check the driver's side light and noticed the same scorching. I pulled the bulb out of the passenger side and re-seated it, and currently the dadgummed thing is functioning properly. I'm concerned about what might have caused the original bulb to come loose to the point that it triggered this rapid clicking, as I have never had to touch the bulb in the 6 years that I have owned this vehicle.

Lights and light housings up until the last couple of years with all the wrap around LED stuff really are that simple. Especially taillights of a vehicle with a lift gate like that. Once you open the gate, the hardware is likely easily accessible nearby. That's how it usually is with truck tailgates and light access.

Need a new bulb

Had to do this on my tundra

Yep this is exactly what I had to replace. Money well spent even though it must be a known Toyota problem.

OP I was doing the same thing... going nuts messing with turn signals. Front right went out so I changed both front bulbs. Then one or the other would be out every other day it seemed. Mine were also scorched black.

My neighbor kept laughing at me every time he'd see my hood up because he said his son just gave up on his tundra. Guess he just drives around without front turn signals.

I had an 05 4Runner and had the same problem. I never figured out how to fix it. Just kept changing the bulbs and a couple of fixtures.
