My left AirPods internal speaker isn’t working

I was cleaning my AirPods awhile back cause I couldn’t hear well through them anymore and I saw something about dipping a Q-tip in isopropyl alcohol and cleaning the mesh with that so I tried it and it worked really well. I could hear out of it much better so I started doing that to clean my AirPods but recently I cleaned my AirPods just like I usually do and they worked fine after but when I tried to use them today the internal speak of my left AirPod wasn’t working and the outer speaker was. There isn’t any wax or anything blocking it and I’m starting to think that maybe my AirPods are broken and I’ll have to get new ones which we definitely can’t afford rn.

if anyone knows any cheaper options instead of getting new ones or if there’s something else I can try to fix my AirPods that would be so helpful!!
