My Jeep is Blowing COLD air!
My 2004 Jeep Grand Cherokee Limited is blowing COLD air when I turn on the HEATER. The car temp is at 208-210 max (normal I assume). How can I fix the heater and is it harmful for my engine?? Thnx!

check your fluid level, if its so low that the water pump can't pump it, then it doesn't make it to the heater core or the radiator. your engine gets dangerously hot and you stay chilly.

Heater control valve or heater core is so plugged its not flowing.
Lol may sound like I'm being a smart ***** but make sure you actually have heater hoses going to the heater core.
Did you have the rig last winter? Did it have heat?
