A/C turns on but won't blow any air!

My a/c will turn on but it won't blow air nor would it blow heated air. Any ideas? Thanks! Is there a ground wire to the A/C? Like on the pass. side next to the fuse box? There is a ground there but the bolt won't tighten like the other ground bolts.

When I turn it on, I only hear the motorized flap thing that goes up and down.

I never touched the A/C but the only thing I touched was the ground bolt next to the fuse box but like I said, it won't go as tight at it was before I messed with it. But I'm not too sure if that goes to the a/c

The blower motor requires a solid ground at ground terminal G203 in order to operate.

G203 is located on the passenger side kick panel below the fuse box. it should have either one or three black wires connected to it.
