Message Aight everyone I got a trickey one here. Some people helped me awhile ago and thank you for the advice.
To the story... So My heater and defroster doesn't work it blows cold air... Now I have searched here and online on Nico etc... However nothing matches my problem really. My heater box is broken but for now if I can get my defroster to work I will be happy.
The problem doesn't seem to be in the heater so I think the real problem is in the engine. The weird thing is I can drive hard and both my temp guages read right in the middle. Last time I posted I ended up changing the thermostat bause my car isn't getting pressure. That didn't work. I have down a flow check, I get air all the way through theheads to the heater tubes by the firewall. I have no anitfreeze leaking anywhere and the flow is not clogged. I still don't have pressure in any hoses and when I take the heater hoses off the back no fluid comes out. The radiator keeps fluid all the way at the top when running and I bled the air out. Any thoughts would be awesome because I am almost at the point of selling it.... not really but, it is making me really angry. Also I have the dash off if that is important.
