bout to drive me nuts , from what I understand, a jeep heater almost shoots out flames they get so warm. I have checked all movment of the selector switches and vacuum modules under the dash, all operate to full out and full in. no vaccuum leaks. still no heat. checked the hoses while at running temp (209) both are good and hot. running aitn-freeze, good and clear with good flow. the temp. selector (blue to red knob) is electronic, could it have gone bad and not allowing the stop-cock to open? It does have a fantastic air conditioner on the warm days, and even a better one on the cool evenings ~grin~

The temperature is controlled by a valve up above the passenger-side footwell, which is connected by a control wire to the temperature control knob. It's possible for the wire to slip off the valve which is, as I recall, visible without taking off the kick plate above the footwell.

Jerry : heater

Jerry, that put me on the right track. When I put the meter on it, it didn't have a reading (burnt out rheostat). However, I did take the valve caseing apart and set it for heat. I'll just have to adjust it manual until I get the part. Again, thanks for the lead....

Now you can crank that heat up when it's 95 Georgia degrees here in a couple of weeks.
Besides, Jeep guys are supposed to be tuff. Don't need no stinking heat!!!
(Just funnin with ya)

You mean newer TJs no longer use the control wire? Heck, I can't keep up with all the changes!

Yep, my 02 HVAC is electric and vacum controlled only. that is one system I don't like on the TJ.
