My heat wont work and im not sure if this is my heater control valve. If it is are the correct hoses attached because one is dangling as you can see in the picture and there is a plastic peice sitting where i believe that hose is supposed to go.

 

that looks like it should be on the firewall on the passenger side on top

 

yes sir thats it cause just changed mine had small leak

 

how much do those things cost now a days?

 

Thanks alot guys... ok now what part of it actually fails? and do you see that plastic piece close to the harness on top of it? What could that be? And Msc300 is yours hoses connected that same way or does mine not look right? Just asking since yours actually WORKS lol

 

really cant tell from pics but i believe all my hoses were connected ill check today and get back to you

 

That is the heater valve. I leaned on mine before and ended braking it real easy. I got a replacement from Aliga for real cheap. Try sending him a PM.

 

I gotta put my 2 cents in on this...I just recently replaced mine as well and I was lucky enough to get the entire unit for only $50...The damn Lexus stealership wanted $396 for the entire unit and the only part that needed to be replaced was the plastic valve itself ...I guess the reason why it's so expensive, is because there is an electric motor and solenoid that operates the arm that opens and closes it...Funny thing too, is that the Lexus dealerships always seem to have this part in stock, since I'm guessing that this part is very common and is known to go bad and start leaking.
