Heater stuck on ?

I can feel heat when I am driving the jeep. The heater is in the off position, and its not blowing heat, Just seeping out. What could be wrong?

every car I've ever owned has done this. Move the temperature selector all the way to the cold side.

Mine does the same thing (It gets close to 85-90° inside when it is 60-65° outside). Not sure what is causing it but I'm am going to look into it this weekend or next. If I figure it out I will let you know.

Your heater control valve is stuck open. Follow your heater hose to the block and you'll find it.
