My 2004 Z has the left Xenon out. Have replaced bulb, switched relays with right and changed fuses. Cannot find fault. Car has ATP single turbo. The intercooler was added in front of radiator in the same place the headlight wires run. Any suggestions on how to check if power is at headlight plug?
Also, are there any plug ins along the wire route that could have been disturbed when installing turbo cooler? The other lights in the left group do work.

 

Bust out the volt meter and hope youre looking in the right place the first time around...

 

Agreed. Check continuity across the contacts on bulb 1st, then if needed, ck power to plug. Work your way back. gl

 

Ballast.

 

guess basic troubleshooting isn't his style... smh, but this is also the same person who asked "what shocks for lowering springs"

 

how do i start a form ?

 

 

Sorry I am not as smart as you

 

yeah, sucks for you

 

I appreciate all the constructive responses I have received forum members that do not have their head where the sun doesn't shine.
Thread is over.

 

everything that people listed is basic troubleshooting that you should have done. dont like me, i dont care. i dont spoonfeed people like you

 

Happened to me, ended up being the clip for the HID and HighBeam wasn't exactly clipped in. Fun times removing a bumper for that.

 

Looks like the ballast is water logged. Appreciate the help.

 

Told ya.
