I've had this happen to me years ago. You can have an auto parts store test your alternator and hope that's it. But in my case, it was a warped head.
why do my lights flicker and interior lights flicker
Your lights may flicker because they power is really low. It is very common for them to flicker when there is a storm out.
power surge. happens all the time
Yea its an electric or body comtrole module .about 400.00to repair at dealer. Will cause lights to flicker off & on and sometimes horn will chirp also while driving
How do I change the head lamps in a 2005 Mailbu
Flickering lights, on a Cadillac STS, is usually a sign of a loose wire. When all of the lights flicker, it is an indication of a loose battery ground cable.
no
Have your alternator tested. They will sometimes do that when they are putting out low outputs at low rpm.
Its the hash-slinging slasher.
Probably your battery cable or cables are loose on one end or the other.
problem resolved
