hi
I've noticed recently I have no heat or defrost on the front system. the rear heat seems to work OK. It blows air just fine, but it's cold.
I have a 93 JDM which has the climate control setup like the LX450, kind of sort of automatic.
the heater control valve LOOKS ok externally, and the cable is being actuated with the temp slider. I feel warm water on both sides of the valve by feeling the inlet and outlet hoses. I'm somewhat confident the valve is functioning but thought I'd look around for other sources before I throw parts at it.
Not sure where else to look as I don't really know how the system works. Maybe the blend door isn't being actuated by the climate control? Anything else I should check?
