switch, blower, wiring between.Could be that the resistor is not locked into place all the way after you put it in....you really have to cram the aftermarket ones into place and make sure they are snapped in. (have fun getting back at it...they are in the worst place ever)if it only works on 5, it is definitly the resistor. So, put a third one in. Theres probly a water leak into the heater box that's getting onto the resistor, shorting it out

96 grand Cherokee heater work with key off?
The source of heat for the system is water/coolant from the radiator circulating through a heater core under the dash. Without the engine running and water circulating, there won't be any heat in the passenger compartment. There is residual heat after turning the engine off, but that won't last long. If the blower fan does not shut off, the resistor has failed.
Where is the blower moter resister found in a 1999 Jeep Grand Cherokee limited?
The blower motor resistor block is located on the underside of the HVAC housing (Heater Box) next to the blower motor. The blower motor is located at the right side of the dashboard. You can access the blower motor resistor block from under the dashboard. A Word of Caution! Stay clear of the blower motor resistor block heat sink - It could be Hot. Incidentally, I have read about people working on their dashboards and setting off the airbag. It is a good thing to disconnect the negative battery cable from the battery and make sure that it can not touch the battery post. Wait at least a couple of minutes for the airbag system to discharge.
Why does the heater fan come on even with the key off in a 97 jeep grand Cherokee limited?

Your heater core and actuator needs to be replaced on a 2000 Grand Cherokee and you've been given estimates of 600 and up for repair What is the cheapest route besides a portable car heater Any lead?
Go to www.wjjeeps.com and type HVAC in the search box. All the instructions are there. If your heater core is leaking, it has to be replaced. You might try some of the radiator stop-leak products and this may work. The Blend doors have known problem of breaking in this model. Replacing the actuator motor won't help, the blend doors have to be replaced. There is an inexpensive aftermarket product that will address and solve this problem call HeaterTreater. Check on Ebay or www.heatertreater.net for pictures and diagnostic information.
