HALP ME I BUILD ELACTRIC GUITAR

lotta these tops are more expensive than entire body blanks i might as well buy one of those and resaw a few tops out of them christ

i have my main guitar but i also have my old guitar. it's not a fancy guitar but it's unique and means a lot to me sentimentally and used to play and sound pretty cool back in the day. it sustained some water damage in ye olde practice space fire but still worked. then gradually over the period of a few years one pickup stopped working, now the other has stopped working as well. so i have a broken guitar, but i feel bad just totally discarding of it, and if it worked i would probably play it regularly.
i know nothing about electronics or guitar repair. i don't know what is actually wrong with the guitar. all i know is when i reach in the soundhole and touch the base of the pickup switch, it makes a humming sound, so there's still something going on electronically. it could just be bad connections to the pickups and/or the switch, or the pickups could be totally dead. also it's a semihollowbody and i don't even really understand how you get to the electronics to fix them in a semihollowbody. BUT if i try to fix it and fuck up, the worst that happens is i have a broken guitar, which i already have, and i might learn something about guitar repair.
so should i:
1. pay the guitar store to fix it
or
2. try to fix it myself

probably a terrible idea

Most electric guitars have pretty simple electronics. Even if you have to replace both pickups it's fairly straightforward. What's the make/model of the guitar?
However...

some water damage

...if the guitar isn't structurally sound it might not be worth it. Does the guitar hold it's tuning reasonably well? If it's a semi with a set neck, did the water get into the guitar around the neck joint?

it could just be bad connections to the pickups and/or the switch

Sounds like the electronics are still grounded, so maybe it's just a loose wire or a dry solder joint. Also if water got into the switch, it could have gone rusty.

If you have an electrical multimeter, you can check the dc resistance on the pickups to see if they are ok. That would be a good first step, unless there are obvious detached wires.

there is a crack near the base of the neck but i can't tell if it's in the neck itself or just in the varnish. the water damage was more than 5 years ago at this point and i did play the guitar regularly for a while in there and didn't notice any problems with the tuning or the crack getting bigger. but yeah i probably wouldn't want to spend hundreds of dollars on it.

it's a vantage vsh, i think a vsh435 based on this page: http://www.matsumoku.org/models/vantage/vsh/vsh.html. again, nothing fancy but i like it because it has a smaller body and thinner neck than most semi-hollowbodies, it's very "playable" i guess.

ha i just looked at it and clearly says VSH-435 on the headstock and on the label in the soundhole, duh
