Ok... So i have this problem with the new cobalt I got.... the Electrical for the Headlamps have something wrong with them.....

There are NO BLOWN FUSES.... Check 3 Times

No Blown Bulbs.

No Cut Wires. Or Melted Ones...

The Foglights Turn on and Work Perfectly.

The Turn Signals Work Perfectly.

The Brakes and Reverse Lights Work Perfectly.

When the Low Beams are supposed to be on, one side doesn't light and the parking lights don't work.. When switched to high beams only one side switches to High Beam and the other don't and the parking light on one side doesn't work...

wiggling the connector turns off the headlights and then the parking lights come on.... I am pretty sure this related to the Harness and its not the headlamps..

Should I just pull the harness and replace it or is this a bigger problem...


Note: If I plug my projector headlamps in... the halos and parking lights don't work when the low beams are on... and the only one side of the highs work...

 

I say replace the harness

 

before u drop the coin on a new harness, just check all the pins/leads to the connector. make sure u have power where and when u are supposed to. also make sure u have a good ground too. if you are missing power to a wire, follow it back and see if there is a break, or a short. a simple test light should be able to do this with ease, and may save you some coin. a cheap test light is less than 10 bucks and works just fine.

 

Checked the pins.... some were corroded and rusted... so i replaced them... crimped nice and tight... still the issues remain...
