I have been suffering for while with an intermittent low beam problem. The low beams would just fail to come on - sometimes they would flicker and at others - simply wouldn't go. My poor baby was becoming a daytime only driver. Very sad.

I came here to the experts and consensus was a grounding problem along with guidelines and recommendations for checking the various ground locations, I admit that I was suspicious of ground circuitry especially since I had installed headers and the law of unintended consequences could have been in force. Murphy has become a close personal friend throughout my life - especially when working on my cars

So I girded my loins for battle, put a new battery in in my Radio Shack Multimeter, downloaded schematics and wiring diagrams and approached baby with kind, loving and soothing words along with a gentle pat on the fender. I started at the headlights and noticed contact realys that could be disconnected and easily checked with a meter. I started on the drivers side, found an open and switched the two contacts and the problem became a HIGH beam won't work problem. Voila! Immediately - probably no ground problem. Maybe still a switch problem - many of you may not know but most GM cars route every light switch through the ER flashers and lots of times that unit fails and takes the lights down.

I did what was obvious to me and checked the other side and found the same pair of relays with a really poor job of wiring one relay connector on the passenger side. It may have been a factory issue and was good enough to get the car 6 years down the road and reduce warrantee expense to zero - or it could be the previous owners work as he installed HID's. Small point. I was able to easily reach the connector, clean up the grunge on the wire, solder it and had low and high lights.

The whole deal took 10 minutes and I consider myself very fortunate. It is an obvious place to check as these lights do get exposed to water and crimped connector is never as good as a soldered one.

Hope this easy fix helps someone else.

Oh, I took the battery out of the multimeter put it back into one of the Christmas toys.

 

Thanks for the post!
It's tips like this that help most of sane.

Good find. Thanks for the info.

 

Congrats and thanks for the post.

Doesn't it feel good when a troubleshooting session is so successful?

I fixed a problem with a fuse blowing on the Camaro yesterday. It made my day. I know just how you feel
