Wow. Am I in trouble now. The guy I bought the truck from put a new engine in. He stripped everything out of the engine compart ment... painted it and put in a new engine. There is no valve on the firewall anymore.. I can put on in but the blue cable is so short I cannot beleave it went outside the firewall though it may have. With no valve I should have lots of heat in the heater position. Is there another valve inside? I can see the heat/def lever operating all of the various doors and they are all working correctly. Could it be a pluged heat exchanger or is there and interior door I cant see.
Thanks for all of you help

ps. I think it must by plugged so I thing I will gently use the garden hose and see what I can clear out
