Why does my Jeep Wrangler heater stop blowing?
Most of the time when you lose all speeds at the same time it is a melted/overheated connector at the 3 wire connector on the mode selector switch. Here is a link to a troubleshooting procedure for the complete HVAC blower circuit.
What to do if your Jeep blower fails?
If you look up in the passengers foot well, you can see the resistor and besides it the blower motor. The motor is fixed with 3 screws. Just wiggle all visible wires and see what happens. If the problem is inside the AC control panel, then there is most probably not much to do then replacing the panel.
Where is the fan on a Jeep Wrangler?
This is the guy in charge of blowing air across the hot heater core, through the Jeep’s ventilation system, and into the cabin. The fan is usually located behind the glove box and when it fails, you may still get cold or warm air through the vents, but it will be at a drastically lower pressure no matter what fan speed you select.
Where is the blower connector on a jeep?
The blower motor sits right next to the resistor or controller (resistor is for manual AC, controller is for automatic AC system), so the connector can be found on the blower motor itself. Since the state of the blower changes after switching ignition off/on, the problem can be inside the AC control panel.
Why is the air blower on my Jeep not working?
I will start the Jeep and the air blows fine, then without rhyme or reason it completely stops (there is no specific duration between work/failure). Depending on the length of the trip, it may come back on again. I replaced the blower motor resistor and I thought that fixed the problem, but unfortunately it did not.

What to do when your Jeep Wrangler heater stops blowing?
A good squeeze on the connector and a push on the red tab cured all that ailed. Research as suggested above but do you also lose wiper/radio power when the blower is not working? If you do, try wiggling the ignition key to see if it will kick on.
