Where is the low side recharge fitting on 1993 MPV?

On a 1993 Mazda MPV, the low side recharge fitting for the air conditioning system is typically located near the accumulator or receiver-drier, which is usually found on the passenger side of the engine bay. It can be identified by its larger diameter compared to the high side fitting. Look for a service port with a plastic cap that may be blue or black. Always ensure the engine is off and the system is not under pressure before attempting to recharge.
