Default hvac climate blower seldom on and off randomly

2000 monte carlo ss 3.8.
everything was working fine when all of a sudden the blower won't turn on. fuses all good, I jumped power to the fuse where it wasn't getting any and it worked normal.

how can I fix this pre fuse wiring? what is the problem? I was actually getting an issue at one time where the blower would stay on with the key off. but turning the ignition hard left off would solve this but since it'* already in the off position it would come on again. this has since stopped.

so what'* the problem with the Hot with key On before the fuse wiring? I tried taking the fuse box out but that will come when I have time. thinking of jumping power for now. could this be loose connection?

anybody?

Have you tested the relay?

Is it automatic climate control or manual? Everything gets done at the relay. It'* behind the dash on the passenger side.
