Toyotas Aircon Econ Button

speaking of TX valves. Most common point of leak on a SW20 mr2 is the TX Valve Aka Expansion valve.

This is the first place I check for leaks on any Toyota.

Brad who makes these TX Valves? Denso? Have toyota fixed the problems by now on the later model cars? I notice the cooling units under the dash of the Prado have changed alot. Like they are one complete unit now?

They changed from a TX valve to a H block arrangement but some of these still leak. Not sure on who makes them but I would assume denso.

Don't know what the really late models use but I would assume H block. We don't get many real late model cars in yet as they are mainly still under warranty.
