2003 Electrical/AC Problems

Post by Peanut0423 » Mon May 31, 2021 7:27 am

It started with my clock randomly resetting (becoming more often), then my radio volume knob stopped working, then the AC stopped working, now it'll randomly surge with my headlights turning off for a sec, dashboard lights turning on for a second, afterwards driving fine. I just wanna know if ya'll have dealt with this and if it's a belt issue, alternator issue, or battery issue.

Update: Forgot that when I turn on my headlights, I hear a rattling sound towards the front right of my car.

Just checked and it’s 2015 so that has to be the culprit I assume. I’m gonna get changed this week and hopefully that’ll solve everything
