a massive overload of that particular circuit... cheers Aussie charlie..........
blow back or blow-by is pressure that builds up inside the engine causing oil to be blown out of vent,oil stick,oil filler cap, or into air breather.. Causes of blow-by ---- Bad PVC valve (Positive Crankcase Ventilation ) Worse case is worn piston rings or cylinder walls - engine needs to be rebuilt. http://en.wikipedia.org/wiki/PCV_valve
There is a dead short to ground in the circuit.
i had the same problem in my 96 jeep Cherokee check to see if your auxilary fan is shot if you are undable to tell just simply unplug the fan and give it a shot this solved my problem
I have a 99 wrangler and have had problems with the wires shorting out or corroding under the box. I had to remove the box and replace some wires, the fuses in the box did not blow.
hi i like nomey
blend door failure is a common problem on 97+ Jeep Cherokee
Can a 2004 Power Tech High Out Put Engine Fit in a 2001 jeep grand cherokee limited 4.7L v8
Bad thermostat
possibly blown head gasket
check pcv it maybe plugged
Most common problem is that the blend door is stuck or broken.
One of the reasons a 2000 Jeep Cherokee heater would randomly blow cold air and then hot air and then cold might be that there is a problem with the hot/cold duct. The air or a vent might be inadvertently blowing periodically.
the horn itself may be screwed on too tight. Remove the horn cover, usually by prying it off, and there will be three Phillips head screws. Loosen those screws a little and that should solve it.

You may have a faulty expansion valve. It may prevent compressor from running long enough to cool your car.
I've had this happen to me as well. I had a 1998 ZJ Laredo 2x4. I found the problem was the PCM. After I replaced the PCM, no more problem.
