do you guys think I can repair a leak in my windshield wiper fluid reservoir myself

it wasn't squirting so I filled it and then it still wasn't squirting so later I looked in there again and it had all drained out, what an antisemitic waste of a couple shekels

I don't have any car cowtools and I didn't look under the car but I assume there must be a gaping hole at the bottom for it all to drain so quickly

so do you think I can fix it myself or do I have to get wallet r*ped at mechanic it's winter so it's kind of necessary to be able to see ig
