On my 2002 vette the front blinker bulbs (orange 4157) are blowing. It may last months or only weeks. I just searched though the threads and did read about cracks in the housings allowing water to get in. I'll pull the housings this weekend and inspect them. While I got them out does anyone know of anything else to look at that may cause the bulbs to blow?

Thanks,
Jim

 

Check the top of your light housings,they are prob melted from the DRL's and letting water in to the bulbs.

 

Thanks. If that's the case, do you think they would be repairable with JB Weld, silcone, etc...?

 

I think it will work, but maybe temporarily.

 

Many members have sealed them successfully using silicon sealant. Some of us have disabled the DRLs (pull thr A2 fuse), which reduces the risk of burning the unit. Replacements can be picked up on E Bay quite cheaply if you decide to replace them..

Heres a How To from the shop manual to show hoe to get to them.

Thanks guys for the info. I'll pull them this weekend. Has anyone used the $24 3157 LED bulbs. I wonder if they'll hold up any better?

Thanks again,
Jim

 

has anyone ever tried the 3157-4157NALL LED bulbs in place of the standard bulb?

Same problem months ago. Like rebelheart said there is probably a hole in the top of the blinker housing. My housing had a quarter size hole. Took a piece of 1/8" plastic cut into a larger circle and used Peramtex black adhesive on it and covered it totally and haven't had a problem. hope that is your trouble also.

 

I just replaced mine last Sunday for the same reason bulb burned out twice way to soon. Got some new blacked out housings and LED bulbs from JW! When my housings came out both sides had cracks not to bad but enough for water to get in. If you bother taking them out to fix get some LED lights in there so they wont heat heat up and crack again.

 

Had the same problem with mine a few months back. The top of both housing were cracked allowing water/moisture to get in and blow the bulbs. Took both units out and used epoxy for plastic. Not a problem since.

 

Also replaced mine with 3157NA LL (amber). works great.........

 

Hi JW.....
didn't know they would cause the hyperflash....that's what mine does.
Not the real fast hyperflash but faster than normal. What's the cost for the cure?
Thanks

 

cure for hyperflash 40-50 bucks and 15-20 min.

 

Plug and play super easy fix have to take the panel under your steering wheel off to get to it. Instructions can be had on JW"s website.

 

I don't even have to respond. My customers do it for me!

Thanks by the way!

The hyperflash harness fixes it. I ran out of flashers this morning I'm afraid. Those are 2 weeks out.

 

Might want to check your owner's manual. I originally had 3157's from the factory, when mine went I checked the OM and it said 3057s.

So I used what the OM called for. (Probably just like the factory installed Denso Platinum plugs.)

Your problem is most likely a pin hole from a rock or something in the lens. They are around $38. for a new lens, I just replaced my driver's side. I tried to seal it but moisture kept getting in there and blowing bulbs. So I saw no reason to further mess with it, I just replaced the lens and was done with it.

There are tricks to replacing the lens if you decide so post up and I'll provide (or someone will) the steps to replace.

Oh yes... mine is a 2001.

 

Thanks Guys so all the info....
will check into the harness and my manual for bulb size.

 

epoxy also works.

 

I use 4157NA bulbs and have never had an issue.
