Replacing turn signal bulb
My front passenger side turn signal is not working.
The rear passenger side turn signal flashes but fast.
So I believe it is the front bulb that needs replacement.
Would I be correct in assumeing this?
And how do I get to the bulb?
Thanks

open hood... turn on headlights... hire a midget or a child to reach in beside the headlight and remove bulb. Thats how i've done mine... luckily i have a young nephew that can reach them and did not have to hire the afore mentioned midget.

I'd say your diagnosis is correct.
You'll get three suggestions for changing the bulb
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 unscrews counter clockwise but it has a plastic clip which you need to squeeze to release it. Change the bulb. Reseat the bulb holder and turn until it clicks back in place. Put the plastic 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.
10 minute job.
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.

I prefer to just remove the access panels behind the front spoiler on each side. That way, there is no chance of scratching anything up. It takes a little longer, but is much less aggrivating.
