Folks, hello from suburban Chicago. I have an issue on my hands that I cannot figure out and would like some input for the great folks on the Forum. The turn signal on the right side of the car blinks twice as fast as the one on the left. I thought it meant a bulb was burned out but all bulbs are good in front and the back?? Anyone have any idea what could be causing the blinker to be going into hyper-speed?? Thanks for any help or input.

Are you really sure about the bulbs?
Make sure that all the bulbs activate exactly the same on both sides. One bad connection or a damaged filiament will give that indication.
Just ohming the bulbs out could givea false indication, Watch them function (blink), then decide. all four corners should blink.

 

If your OEM flasher is the cause, i have the fix for ya.

Guys, thanks for the input on the turn signal issue. How do I get access to the bulbs in the front of the car?? No screws on the outside so I guess you need to get in from under the hood, right? Any tips on getting them out and changed? Thanks

acess from the underneath... or turn the headlights on and remove the plastic surround and reach down

 

Don't forget that the turn signal bulb is a multi function dual filament bulb. It gives you DRLs, parking lights and T/S. You can have one function failed but the other working and the car will tell you theres a problem by rapid flash.

Change the bulb anyway and see if it fixes the problem. You'll get three suggestions on how to change it.

Go in through the brake ducts - not easy with a Z06 or if you have screens

Go in through the bottom by taking out the bottom panel



The one that works for me is:

Turn on the headlights and back off one position to kill the lights.
Unscrew the 3 small screws on the black plastic housing around the headlight. Gently pull the housing clear. Reach down around the headlight unit and release the bulb holder. It comes out by turning the bulb holder a ¼ turn counter clockwise but it has a plastic clip which you need to squeeze to release it. Here’s how the bulb fits into the lamp unit. The DRL bulb is the lower of the two.



Here’s the light socket. This one’s after market but it gives you the idea. You can see the clip you need to squeeze.



Change the bulb. It’s a push fit into the lamp holder. Push it home firmly but don’t handle the glass. Use latex gloves if you have them. Reseat the bulb holder and turn clockwise until it clicks back in place. Put the plastic headlight housing back in place making sure to locate the small plastic tab in the bracket on the headlamp cover. Replace the 3 screws and close the lights.

It’s a 10 minute job. Some guys have had the lights close if they’ve taken a while to do the fix. If you’re worried about that, disconnect the battery once the lights are up.

The bulb is a 4157NA

Some guys with big arms remove the hood adjusting screw for better access. Guys with even bigger arms have had to take off the headlight cover. Four torx screws (2 back, 1 each side). Take the back ones off first with the lamps down. Raise the lights and take the side ones out.

 

You can go thruogh the front brake air ducts no tools required. You tube has a guy demonstrating this.

 

Nice write up, DeeGee!

 

My bulb is good on the front passenger side. Checked it on the other car. Parking light works but it won't blink. I was thinking flasher. Talk to me goose.

 

had same problem on my 98 . change the bulb . the multifiliament bulb will fool you into thanking the bulb is OK it's not . best way to get there is to remove the plastic shroud from around the headlight . 3 screws good luck
