2005 Suzuki Forenza My low beams wont work

Electrical problem
2005 Suzuki Forenza

Yesterday I noticed my lights not working, so I switched the fuses out and they worked, then later at night they weren’t working again. I tested the fuses under the hood and they are still good, and neither of the headlights are burned out. My dad told me to check for corrosion, but I didn’t see any anywhere. Limited funds are keeping me from going to a mechanic
