you know the 2 hoses come thru the firewall , the rubber that goes around them was broke into a million peices since its been replaced 3 times ...... so we left it off ..... could this b the problem?!
try putting the blend door back in and opening half way, yu might be able to close off the cannister enough to make some heat
ill brb i will check my hoses on my firewall cause i think i broke them too but i still have heat so that might not be your problem
