Turn Signal & Flasher Problems?

**Hustler** · 06-25-10, 08:36 PM

As many of you have or will have, I had been suffering with turn signal issues for over a year. It was tolerable but annoying at first, then turned into a PITA, then became a safety issue. I scoured all the boards looking for a fix. I had already tried the WD-40 and even electronic contact cleaner, but nothing seemed to work and neither solved the problem. I dreaded removing the top of the dash which is the recommended procedure. Removing the radio was also said to be possible, if you have small hands. That option didn't excite me either.

While doing my research I did read some comments that stated a device built for LED tail lights solved this problem. I went to the website, read the description and was surprised that this simple device was available, affordable and was easy to install.

I called the phone listed, purchased the item, followed the instructions and in less than 30 minutes, my problem was solved. If you are having this same turn signal issue, I strongly urge you to order this part and if you can remove 4 easy to get to #15 Torx screws, you can fix this while having a cup of coffee.

If you want to spend a few more minutes "fixing" an issue of this type, you can do it for about $13, not $69. An EL-12 flasher from your favorite auto parts store and a little labor will do the same thing. Below is the procedure for DIY Flasher Bypass.

Nick,
Thanks for the info...looks simple enough and eliminates that PITA dash/ switch removal!

I decided to visit my local Advanced Auto last evening and pick up an EL12. With PA tax it cost just under $14. This morning I decided to tackle the job and found the following:
Total time involved: About 30 minutes, start to finish.
For our 2000, I had to remove 2-#15 Torx screws from the bottom of the panel, and one Phillips head screw at the air sensor. I carefully pried away the panel and disconnected the 2 wiring connectors, one for the sensor, the other for the driving/hatch switches. Locating the harness was easy (credits to CG, AKA Nick), and I decided to give myself a little extra working room, so after cutting the pink and purple wires, I added 6" of 16ga. wire to the female terminals, then crimped them on, connected the flasher, test all, and reversed the panel removal procedures. I tucked the flasher adjacent to the lower driverside front console after wrapping 1/4" foam around the flasher - for rattle, protection and ease of replacement, if necessary. A Piece of Cake!!!!! Thanks!!!!

Great! I'm glad I could share some knowledge. It is always appreciated when I can use some small bits of information other people have learned.

Hey,

i did it that way but have a big problem now. The right flasher works perfectly but nothing works on the left side. The hazzard flasher works well on all four edges.

Did someone has an idea?

**rch105** · 10-15-10, 02:27 PM

Andy,
It sounds to me that you may have not crimped a wire hard enough to make the electrical connection, you may have pulled a wire loose, thus not making contact, or the connector(s) might not be tight. I'd have to say it's in the wiring if it had been working. Check all our wires and connections,let us know what you find, and good luck!

**Curious George** · 10-15-10, 05:01 PM

It may be possible you cut the wrong wire(s). I apologize for the low resolution picture image.

Go back and double check to make sure you cut the right wires (and you have used the correct "ends" of the wires) and as RCH105 said, be certain no wires came loose from the new flasher.

I would suspect that if one of the two wires came loose from the flasher you would not have any operation at all from the turn signals, but I have not tested that.

**BoxsterAndy** · 10-16-10, 11:09 AM

Thanks for your idea, but the crimp was okay. The right side works perfectly but i have no luck by the left side.

Other ideas?

**hotmtrsports** · 10-16-10, 01:11 PM

I'm following this thread...

I know this has probably been told, but could you please briefly describe the problem so in case my friends describe this problem.

Thanks,

Chuck M

Andy,
Before you started this flasher modification, did your turn signals work properly? You never stated why you were doing this modification.

There would be two reasons a) using LED type bulbs instead of incandescent bulbs, and b) there was something wrong with the OE turn signal circuit.

If you have cut the correct larger purple and pink wires and connected the EL-12 flasher correctly, then the turn signals should work.

Don't mean to sound insensitive, but are you color blind? Maybe have someone else look at the wire colors.

So let me tell you the whole story:
in the middle of last year i had the problem that my flasher front left does not work anymore and the flasher back left goes quick. I fixed that by change to a new original hazzard flasher. From that on everything works fine.

And now, nearly one year later i had exactly the same problem again. I also changed to LED lights in the back, but they flash fast.

So i tried to fix it with the bypass. And it works very well for the right side, but with the bypass i have NO (not front left and not back left) flasher on the left side. So i put the wires back together without the bypass and had the same as before:
no flash front left and fast flash back left!

Hate to sound so basic but have you checked the fuses?

**BoxsterAndy** · 10-30-10, 02:35 PM

Did the Corvette have a fuse each turn Signal or One for all turn Signals?

Just wanted to say thanks to CG for the flasher mod. Bought a 2000 convertible M6 last week and the turn signals went out yesterday. I'm pretty handy with wiring so I decided to cut the wires and put the electronic flasher in place. Took me all of 20 minutes. Unfortunately, a former owner seems to have been less than careful removing the dash panel, and the panel was broken where the two upper screws connect it to the dash. Having a PhD in RE (redneck engineering), I fixed it by epoxying a couple of 1/4" washers I had sitting around to the panel. The epoxy is curing now. Probably could have gotten away with the 5 minute epoxy, but the two hour stuff is 50% stronger and I'm not going anywhere tonight...

Also, for those looking for LED bulbs, there are several places online that sell them for a lot cheaper than Autozone and places like that. What's the policy on posting links to non-sponsoring vendors on this forum?
