DRL, turn signal malfunction

[Z16Jim]

Need some help guys, yesterday went out for a drive. when we were coming home some one in front of us pulled over and got me to stop. they told me my DRL were going on and off. Can anybody tell me where the ground is for that front harness? I am going to clean all the contacts for the bulbs, to see if that helps.

There's 4 main ground connections. Marty just went through his on his C5. Send him a message. I bet he'all be able to help you out.

Thanks Riley do you know his user name?

Jim it is just "marty" on the forum. I have the manual for the 03 but cannot look it up until tomorrow but I will gladly help you if for some reason Marty does not see your request. Interesting that the person would stop you to tell you the problem, it is one of those things you are unlikely to find out on your own.

not sure which one is specifically for the DRL. I would imagine one of the front 4.
probably not 6 it's just a single ground wire/strap to the engine
but 7,8, or 9. might be good to make sure they are all clean.

Thanks Marty, this will give me somewhere to start.

went out and took a couple pics. some have gone as far as unplugging the terminals and using some di electric grease.

 

[marty]

let us know if it works

 

[Z16Jim]

great pictures they help a lot, going to garage to clean them up. Thanks again.

not sure if you can read a wiring diagram. I can't, but I think this one says ground are at the 101 and 102 locations.
which would be the ones I indicated in the photos.

good luck

I got number 7 and 8 will work on getting 9 later

 

[Z16Jim]

I did #9, going to do di electric grease to as many of the connections on the front harness as get at. Thanks for all the great help today!

Great information. Thanks Marty and Jim, and I hope this problem is sorted for you.

I think every thing is ok now. I will have to follow the wife in her car and get her to watch and see if they misbehave. Thanks for great pictures and wiring diagram Marty.
