A vehicle air conditioner has two basic components; the compressor, and the fan, or blower. If the compressor is working, the air coming out of the vents will be cold, but if the blower is not working, the air will not come out very fast. Hot wire the blower to the battery, to bypass any fuses or switches, and see if the blower will run. If it does, but will not run when connected normally, check the fuse for the blower. If it is good, you would be wise to take the vehicle to an automotive electrical specialist to have them troubleshoot it.
