Front Turn Signal Issue

[sport2004]

I replaced the front passenger-side socket and amber bulb a year ago December, and now it is malfunctioning again...:ybrick:

Why...?????

Any ideas appreciated...

Maybe water and road salts are getting into the housing and causing corrosion of the socket, what does the socket look like now?

thanks for asking, have not inspected it yet, but needless to say i've done very little driving in the last 6 weeks. In that time frame there's been no road salt in use, and i would say i've driven in rain a handful of times.

maybe i'll just chalk it up to annual maintenance...:ybrick:

Yes I'm sure with all that going on in our world today you might not have driven it much lately...but from reading your post the "new socket" is over one year old and did see the road during much of the winter so if the seals on the blinker housing are bad it very possible that some slushy road snow/road salt could have gotten inside and started some corrosion and once corrosion starts it continues even if no more slush got in and eventually the corrosion will build up to the point you lose connection in the socket, which is my guess, but the only way to know for sure is to take the socket out and inspect it and the bulb for corrosion.

the Toyota part # 81125-35440, is called headlamp Cord per Toyota. I used the same number when looking up Amazon.

those new harnesses are holding up fine, maybe 2 years now. One is Toyota, One is Amazon, no problems.

there appears to be no deterioration of the components. I wonder if the wire hook-up into the back of the socket is the culprit

Even with no corrosion, you could still have a lack of connection between the bulb and socket contacts, or where the socket seats into the housing, if I'm not mistaken the socket connection to the housing creates the "ground" completing the circuit, so it could be any of these causing the issue, as well as you suggested the wires going into the socket, there also could be an issue with any other connections between the socket wiring and the main wiring harness.

thanks. the fit and eveything else looks pretty tight, will keep messing with it.

Have you tried swapping bulbs or trying a new bulb?

That should tell you if it's a bulb or the socket that causing the issue, I would try the bulb that is not working in the other turn signal to see if it works, or test it with a multi-meter for continuity to make sure the filament is not broken, sometimes a bulb's filament may look intact but has a very small break that's not visible to the eye.

Thanks, I would go through the trouble to do that if this wasn't the second time around. A bulb should last longer than a year and a half. I also replaced both at that time, even thought the left wasn't malfunctioning. Regardless, I may still have an extra to test with, but I doubt it's the bulb, and if it is, that would mean something else is causing it to blow prematurely, no...?

If a bulb blows repeatedly then yes something would be causing that...but a bulb can blow at any time for no reason at all, other than it blew out, but usually it not too common, but just because a bulb blew 15 months later doesn't means there's something that caused it.

All bulbs have a "life" cycle, meaning that they will generally light up a certain number of times, or a certain time frame of being lit up before the bulb dies/blows out, not sure what that would be for the turn signal bulb.

That being said, yes a bulb should last for longer than 15 months.

i don't think i turn right more than i turn left...LOL

 

[sport2004]

replaced the bulb and it works...we'll see if an underlying problem causes it to go prematurely

After I bought my new to me 2004 4runner I went through 3 turn signal bulbs in less than 2 weeks. I decided to change the socket and haven't had a problem since. Good luck!
