check the heater hoses to see if hot if so then you might have plugged heater core or the blend door is stuck or broken

That is not what you should have done. You should have taken your Jeep to your dealership or local mechanic and have them run a diagnostic on the heating system to see if it works properly or not. Also, heating systems can run you between $300-$1,000 depending if it could be the blower itself or if it could be the whole heating system.
Also, sometimes the heating system could be working "overtime" because of how cold it is outside. So you should be patient with it in the meantime before you take it to your dealership for them to check it out.
