Test car expansion valve run the engine at normal speed until the gauges stabilize—needles move in a predicable pattern. Most clutches are checked using a feeler gauge. Cleaning or replacing the air filter may help, but cleaning an evaporator coil requires an air conditioner service call. Start the engine and turn on the ac to the max (recirculate) position and the coldest setting, along with the highest blower speed. Notice the frost at the expansion valve's port above, where the refrigerant is metered into the evaporator core. 3d air blowing, sleep mode, and other air blowing modes. In some air conditioning systems, this function is handled by a thermostat. (txv) thermostatic expansion valve air conditioning systems contain a receiver drier that cleans and absorbs moisture from the refrigerant. Service couplers must be connected to a refrigerant hose and the refrigerant hose must be connected to a manifold gauge set with both low and high side valves in the closed position before connecting the couplers to an a/c system.
