How to remove the A/C expansion valve on Mazda 6?

There are several ways that air conditioning systems convert the high-pressure liquid refrigerant from the compressor to lower-pressure vapor. The conversion takes place at the air conditioning evaporator; the evaporator is chilled as the refrigerant passes through, cooling the airflow through the evaporator for delivery to the vents. The conversion is usually accomplished by a sudden change in the tubing size. Many vehicles have a removable controlled orifice in one of the AC pipes at the firewall. The models covered use a thermostatic expansion valve (TXV) that accomplishes the same purpose as a controlled orifice. To remove the TXV, have the air conditioning system discharged by a licensed air conditioning technician, then disconnect the refrigerant lines from the TXV at the firewall. Remove the two bolts securing the valve, then remove the valve.
