I'm really confused. With the colder weather coming there's alot of posts about YJ heaters. They don't even do anything. I mean i have mine on full blast on a 40 degree day, i feel nothing but cold. My heater blows very hot air, and blows out strong, so nothings broke...Is mine messed up or do YJ heaters actually work?
