To repair the AC in a 1999 Infiniti QX4, start by checking the refrigerant levels and topping off if necessary. Inspect the AC compressor, condenser, and hoses for any leaks or damage. If the compressor is not engaging, test the electrical connections and fuses. If issues persist, consider seeking professional help for more complex repairs, such as replacing the compressor or other components.
