Why my 2002 Civic Si doesn't blow air when A/C is turned on?

I did the self diagnosis that Hondas have for the AC system and i get trouble code 12. The ac light turns on when if turn it on but nothing happens( no air)

I replaced the blower motor relay and still doesn't work but when i put a jumper wire from blower relay terminal 3 to 4, the whole AC system works normal with no trouble codes. The blower relay terminal 2 doesn't have 12 volts but blower relay terminal 1 has ground.

is it good to just jump the relay terminal? I would prefer to have it fixed right.

A wire from relay to under dash fuse #14 was cut around the fuse box. It was a thin black and yellow wire
