Hey,
Sometimes when I drive the battery warning light blinks from bright to dim for few minutes and then turns off and once in a while does it few times when driving. A week a go I had a long drive about 6 hours and at night the light started blinking again and didn’t stop for 15 minutes then ABS light starts doing the same thing then Air Bag light….then all illumination light for speedometer start going dimmer and dimmer, headlights went dim too

….so I start exiting the highway and while turning I head this quiet but still easily noticeable “clunk” noise and all is back to normal like it never happened

. After that I got a couple blinking battery light few days later…..I will get the battery checked but I was wondering what else could there be? And I don’t know if it matters but every times I start my car, for headlight and heater/AC to work I need to turn the key maybe 1/8th of an inch back so it would click once the car is already running. Thank you for help
