Is it just on one setting what about defrost ? If it happens on all settings then its Probably the blower. Check relay/ fuse and make sure its getting power.

So is the blower coming on at all? My jeep on speed 1 barely blows anything. If it is blowing on a single speed it is probably the resistor for the blower motor. If it were a fuse it wouldnt blow at all, and usually if its the blower motor it either works or doesnt. The resistor is actually what controls the motor speed.

Can you hear a change in blower motor speed on the different settings? Also, does the problem occur on defrost, dash, and floor positions, or just one?

I think I can hear the motor not really use its very lose tho and on all setting ac low or high heat defrost ect on low or high barely comes out. You would know its on unless you put your hand right up next to it to feel the very little that's coming out.

The blower motor comes out in the engine on the passenger side. Its the black piece coming through the firewall. Pretty easy to replace.

The fan could be full of grass, do you have rodents around? If you leave the hood open, then squirrels can get into the fresh air plenum through the hinge openings and build a nest in the fan.
