Four Seasons A/C Expansion Valve P/N:39388
Four Seasons 39186 front a/c expansion valve for the 2007-2012 Toyota Camry and other vehicles regulates how much refrigerant flows into the evaporator in the A/C system.
Weak cooling or vent temperatures that wander can mean the valve is sticking or restricted, but a leak or low charge shows up the same way. With the engine off, look over the valve and its fittings for oily residue or damage, and leave pressure testing to an A/C shop. The 2008-2013 Toyota Highlander and 2007-2010 Toyota Sienna are also on the fitment list, at one valve per vehicle. If your car is something else, look up your year, make and model in the "Vehicles it fits" section before you order.
