my civic heater isnt really workin properly. it throws out warm air not hot air. and my windows are getting super foggy. and the worst part about it its that it just started to snow 2 days ago. so its sucks really bad. i was wondering if guys had any clue whats going on with this issue.
if you guys can help it would be great..im lookin foward to fixing this quick before the snow get heavier. thanx guys
also...my heater does not work on 1 or 2..only on 3 and 4

 

Bad blower resistor or fan switch.

 

thanx ron j.!
