I need help with electrical stuff on my truck!


Recommended Posts

I have a 2005 Chevy Silverado 1500 5.3
I'm having a problem with my lights, at night when I turn my lights on, the blinker lights stays on in the dash, and the actual lights slightly stay on in the front, rear, and on the mirrors. When I turn a blinker on, both sides flash, and when I hit bumps or slam a door it fixes it temporarily or makes them work slightly better. My headlight dims and brightens aswell when hitting bumps or slamming a door.
The turn signals work fine when the headlights are not on.

I'll follow this thread, mostly out of curiosity.

 

Can't tell you where, but somewhere is most likely a connector that an authorized GM TSB will say the fix is to unplug and replug the connector. Have had more electrical 'oddities' and outright failures in my 05 'Burb than in all my other vehicles over my entire life (including some with 1 set of wheels already in the junkyard).

 

Ground is also often a big cause in electrical issues.

Sorry I won't be the most assistance here but it definitely sound like you have some crossed wires somewhere in your system. I'd start looking at all the wiring, especially in the door jamb area and see if there is anything that stands out as being corroded, burnt, disconnected or just seems wrong.

Yep, Im going with a pinched wire or something grounding out against metal and youre getting backfeed through wires. Have even had that happen with an 1157 bulb, the elements in bulb were touching.

This thread is from 2015. More than likely it was a ground wire issue.
