hey guys i have a 96 honda civic with a b series conversion and i need help to figure why my heaters are not blowing hot air like a normal car should. When i set the heat to come from the engine and not having the fans blowing it out there is no air coming thru which in my other hondas air usually comes thru, warm air does come out but it should be alot warmer it also takes ages to defog my windows.

I have checked my thermostat and it seems to be working fine.

Thanks alot guys all the help will be appreciated.
