Re: Jeep Grand Cherokee 2001 blower fan resistor...
Hy almare - I would take it back. Did you buy it from a junk yard and were hoping to make it work or did you buy from auto parts store and they gave you the wrong thing? I would take it back and get the right part . Try another place if they don't have it. Or go yo the junkyard and there. You shouldn't have to jimmy rig that connection. Thanks.

Hi, have you check the fuses, if they or good check and see if you have power at blower motor resistor and none at blower motor replace resistor ,if there is power at blower motor replace blower motor.Thanks if i can help just re post.
Check resistor block . He'll find it where connector was plugged in under dash or near it. Quite often when resistor goes, you'll get only high fan for a while,then nothing. He can check for incoming voltage to that resistor as well. Normally will be a 2" x 3" roughly with connectors sticking out and held in with 2 small screws into duct work area.
sounds to me like the blower motor resistor, and if I'm not mistaken the resistor and the blower motor are located under the dash on the passengers side. the resistor should have a wiring connection and 2 screws attaching it to the blower case. The a/c and heater blower will not work if the resistor goes out. hope this helps you out a little. Best wishes.
As the circuit is through this resistor, and the main load is the blower motor, I think this is taking a higher current than normal to make it turn. You could simply fit a lower rating fuse to the circuit - as this is cheaper to replace, and check the fan to make sure it is easy to spin by hand. If not, try and oil the bearings as a last resort before replacing it.
You have to change the resistor (little box that the blower wires goes to) it is held in with 2 screws you will need the harness (($15) as the factory one was a defect and last you need to change the blower motor as the factory one draws too much power and burns up the resistor and harness..this is what i did on a 2000 grand cherokee with the climate control and it works great..I tried to fix the harness etc but it will still go out again if you do the above you will not have any problem with the blower working at random it will work better than new.I think jeep has retards for electrical people, has anyone had problems with the junky taillight assembly??
Try wiggling the connector on your Blower Motor Resistor. They are known for having a bad connection and melting the connector. Check on Ebay, I bought a new harness kit on there. It was easy to install, just cut off the old connector and splice in the new. The colors match so there is no guessing which wire goes where. Only cost me $12 and saved me $300+ that the dealer wanted.
