I have a 2006 trailblazer and apart from the usual oil change it's been good for me 13 years and still running great.

The passenger headlight bulb and plug-in connector burnt out on inspection the two prong connector had erosion on one of the connection pins, also has signs of heat ?

I'm not sure if I should just replace the plug and bulb or look for another problem ?

If anyone who could point me in the right direction it would be appreciated...... Thank you

 

Just replace the connector . This is a known issue where some will burn out the connector. I suspect they didnt use a heavy enough connector along with the fact that the headlights are on all the time once you start the vehicle unless you are like me and turn the DRL's off when you start the car .

 

Thanks for the reply Vipergg22. I took your advice and replaced the connector so far no problems.
