My apologies if this is a repeat question, but my left headlight, right tail light, and the dashboard lights on my 2008 Optima are out. I change the corresponding fuses and all the lights work for a couple days and then go out again.

I would appreciate any feedback on what is most likely the issue as well as if it’s something I can fix myself. Thank you!

Are the fuses you replaced blown? If not, then there might be corrosion in the fuse block making for a bad connection over time, and temporarily fixed when replacing the fuse by contact wiping.
If the fuses themselves are blown, then something is shorting out and causing the fuses to blow. That is a much more involved troubleshooting process.
