Heater Fuse
 
I realized yesterday my heater isn't working-the fan blows, but no hot. (09 JKU). I checked the fuses, but couldn't find one clearly labeled "heater". Found a few with hvac, but those all looked fine.
Is there no fuse unique to the heater?- was it those hvac fuses?

It is of course still under warranty, but I thought I'd trouble shoot the simple stuff before bringing it in.

Any thoughts?

if the fan blows, you don't have a fuse problem you have a heater core problem.. reach under the dash and touch your heater core. if its cool or luke warm try back flushing the heater core. oh and check the T-STAT.

Yeah, not a fuse issue, probably a thermostat. Take it in, get it fixed under warranty.

Could be the cable to the heater core box also. I install some audio stuff and my cable popped off.

That's a good idea.....wonder if the OP had the dash apart?
