ok, so i have a 95 4.0 2wd Cherokee sport. When i run the AC or Heat blower motor it runs GREAT for a few seconds to a minute.... then it abruptly kills the entire car.... any ideas? i did a few experiments to try and pin point the issue but its looking like the blower motor.... any other ideas? could it be a resistor, a relay, the blower motor itself, faulty wiring etc?

AC Blower Motor:
experiment 1 fan low/ 2 fan high) idle (cold start) turn on AC runs great then abruptly dies (power goes off, gages turn off and motor die at the same time)

experiment 3 fan low/ 4 fan high) run about for 10-15 minutes (normal running temps) turn on AC, same results as experiment 1/2

experiment 5 fan low/ 6 fan high) turn on heat, mimic experiment 1/2, same results

experiment 7 fan low/ 8 fan high) turn on heat, mimic experiment 3/4, same results

experiment 9 fan off, vent cold) runs a little bit longer but same results as experiment 1 & 2

experiment 10 Fan off, Vent heat) same results as experiment 9
