2012 chevy avalanche......lights flicker, be it the dome or headlights......put a new battery and alternator which helped a little......checked the ground off the engine to the fire wall and the ground off the battery to the front of the frame, i cleaned them up.......i know this is a loaded question but are there any other ground locations? .....i didnt check directly off the negative cable at the battery though as of yet, but just wanted to know if anyone else knew of some hidden grounds that would make this problem happen......no codes on the dash .....wish it was an easy fix as the headlights drive me crazy as they pulsate against the garage door at night......i put di-electric grease on the frame ground and i got a dash engine light so i cleaned it off and the dash light went away and the headlights were also dimmer when i had the grease on the ground......im assuming its all a ground issue making the lights pulsate.......im no electrician and dont really understand electricity........any suggestions would be greatly appreciated
