i got this bathroom faucet where the hot water doesnt want to run. the cold water runs, the knobs underneath the sink are on. i just dont know enough of plumping to figure it out. my aim is to replace the whole thing in the future, but not right now. i just need to get the hot water on. basic info: it's an older faucet with both a hot and cold water handle, it's in a bathroom thats built in an "in-law" and probably shouldnt even be a bathroom. but i doubt the pipes are dirty, it's simply not that old. all other pipes in the house work fine.

i thank you for any info you can share.
