I recently just acquired a 1990 Chevy Cavalier as stated in the headline. It's a 2.2L inline four. This car is only used for strictly to and from work and nothing more so this issue isn't a huge deal but just more of a headache.
It is by definition a beater but a car never-the-less. There is only one problem that has plagued me. If I get off work late and have to drive at night after a little while into the trip the headlights just flicker on and off with no apparent rhyme nor reason. Just out of nowhere they go mad. It's not like a set timing, it can be after half an hour of driving or thirty seconds.
I have checked the fuses and lights and they are all fine, the battery is new. I'm assuming this is just a bad ground but even if it is I don't know how to check for even that and I don't know how to even fix that. (I apologize for such a n00b question.) The tail lights/running(parking) lights do not experience this problem. It's strictly the headlights.
It does it regardless of being high beams or low. They just start freaking out, if I turn just the running lights on and then pull it back out so that the headlights are turned back on it will fix it temporarily (But sometimes only lasting maybe a block at best).
I have a video of the problem, but I highly doubt that will add anything.
I'm just trying to diagnosis this problem and hopefully figure out how to fix this dumb delima. I picked this car up for 500 dollars so I wasn't expecting much but headlights are important, I've already been pulled over once for it. I just want this headache done with.
TIA
