The jeep has randomly losing it's power to the blower fan. A/C Kicks on, cold air seeps through at high speeds, just no fan. It worked great for a few months after the first hiccup, just recently it's been worse. It may go out after 20 minutes of driving or may last all day...I'm wondering if it's the motor or the swithch...
 
Common problems are the dashboard switch, the wires, the blower motor resistor, and the fan.

Inspect 1,2,3 for signs of damage or overheating. Apply 12 volts to the fan and see if it runs.
