Ibasket I will check my dash vent discharge temp soon and let you know what I find.
My TJ is OK as far as output. I never run the fan over the 2nd position after it melted down the heater control.
I guess it all depends what your used to.
Replace your HVAC Blower motor. As they age, they draw more and more current which results in blown resistors and melted connections. Its a pretty easy and straight forward job. New motor costs $30-40 for generic- $100+ for Mopar.
Unfortunately this has nothing to do with OPs lack of heat. Mine gets quite warm even though I have issues with it blowing out of the selected vents and a missing piece of the intake duct causing cold air to come in behind the dash.
