I have an 06 Dodge Dakota V8 112,000 miles. Lights will dim or flicker while driving. I went to roll the window up last night and the headlights dimmed. I have taken it and had the battery and alternator tested at autozone. What should I be looking for?

 

 

Bad grounds, Worn electrical equip pulling high amps. A power window in a bind will dim the lights,

 

the battery and alternator tested normal. This morning on my way home the clock light went out, the dashboard lights kept flickering, and the fuel gauge kept moving a little bit.

 

 

I once had a car that had spent some time up north. Had some similar issues - weak starting, power windows and power seats dimming lights. While wiggling wires the main ground cable felt funny so I cut it open and a bunch of white powder fell out. I scraped the corrosion off and i had maybe 50% of the copper left.
