    TJ Little to no heat

    So, Drove the jeep to work today...I dont know why...

    Im getting little to no heat in the jeep. I haven't done any real trouble shooting yet other than verifying that the blend door seems to be moving..

    I plan to grab the heater hoses after i get home tonight and see if they are warm. Any other ideas?

    I guess this is karma for being spoiled with a heated steering wheel for the past couple weeks...

    Heater core clogged inside so water can't circulate through it?

    Do you have plenty of air flow coming thru the vents?

    Blend door would be another guess but you say it seems to be moving.

    Vacuum leak on the heater valve under the hood? Or it could be seized keeping hot coolant from even getting into the cabin.

    The radiant floor heater isn't enough?

    Honestly haven't lifted the hood to look, but in not sure the TJs have a valve.

    Don't think they do, coolant flows through heater core all the time. Assuming your engine was up to temp (thermostat not stuck open), it's probably time for a heater core. Good thing you don't have a cage through your dash ;).

    Mine has been clogged twice and does what you are describing. I flush it with the hose pipe and its back to good.
