Three years ago, I installed a set of Morimoto LED lights on my 2006 C6. Very long and tedious story, the short version is shortly thereafter, started noticing a flickering. Morimoto gave advice to check things but it's a b***h accessing the lights if you live in a rainy area with no garage. Ended up controlling it by simply setting my headlight switch to "headlights on" and not Auto. Seemed to work fine; no flickering, no one complained about me driving around all day with them on. Then, one day lights went crazy and couldn't turn them off, even with the car on off. Discovered they would go off if I removed the low beam relay in the fuse box. But if I let the car sit, the battery drains after a week. Convinced Morimoto to treat it as a warranty and they sent a new driver's side light with all the controls. Unfortunately, that didn't solve the problem. See some old discussions about flickering lights but none that seem to apply to the C6. Any one else dealt with this?

you ever have the low beam recall done?? I wonder if you have an issue in the fuse box related to that causing the issue

(Interesting. No, never heard of a low beam recall. Will look it up. Thanks!) Ok, getting old. I do remember years ago, my low beams just died....sort of..would do the on and off thing. Heard about a bypass wire to be installed on bottom of fuse box. (Must have been the recall.) So I removed the fuse box and with a magnifying glass, found a wire with a nearly invisible break in it. Soldered it, beams came back on and no problem since. My instincts have kept telling me the problem is in the fuse box. Will pull it this weekend and see if the solder joint is still good or if there is another break somewhere else.

Mahalo!!

well, good luck I just thought I would throw that out there since a new light didn't resolve it

I’d be suspicious of the low beam relay. Cheap enough to swap out.

Thanks...I did swap out and worked for a while then the problem returned.

I had the low beam flickering then no low beams at all. I did the jumper wire in the fuse box, and that solved the problem. Find the You tube video on "no low beams on C6). If you run into some problems. let me know I have pics of how Idid the jumper wire. Everything has been fine since......at least 2 1/2 years.

Pulled the fuse box out and opened it. Found my old low beam jumper ( which I barely remember installing five or six years ago) was still working. Did another connectivity test of every wire between the fuses and relays and found the wire to the fog light relay was burnt and broken. So ran another jumper. Too late to put back in car last night and may not have time to work on it till this weekend. Hopefully that's it.


Wire on right goes to low beam relay. New wire on left goes to fog light relay.

Cool, hope that was it

It was!! Also, noted that the numbers on the tops of the relays were not all facing in the same direction. Noted that one black one had five posts rather than four which forced the orientation for at least that relay to the front. So I orientated all the rest to the front. I always had a notion that they had orientation issues......OMG, things on the car started working that hadn't worked in years...was getting read to replace the drives seat motor base....no need, working; error code on dash, gone. Memory for mirrors, working and the car is running like it hasn't in years..............

Awesome!!! Glad it worked out.
