2001 jeep Grand Cherokee blower motor won't work on any speed

When i turn the A/C on the compressor comes on like it should, but the blower motor does not come on at any speed. I assume its not the resistor since it wont come on at all. could it be the switch? I'm new to this vehicle. I'm in FL and its HOT!

    I already replaced the blower motor and still nothing, but i just now looked at it again and found the resistor and resistor plug burned up. thought if that went out it would only work on High speed. oh well. part is ordered and ill be cool tomorrow :)

  • xx87gt306xx May 26, 2009

    I can do that, but It'll have to wait till tomorrow.

    Couldnt figure out how to get the pics small enough so here they are on photobubket. they are the first 2 pics. the resistor has 2 plugs, one for the blower motor and one for power/ground ect. the plug that burned up was the one for power/ground. It was the black wire that burned up. A/C works fine now. The old part was dated 6-06. kinda weird it only lasted 3 years. POS parts i guess.

    Your welcome. I replaced the resistor this morning and the a/c works fine now.

I had been searching for a blower motor resistor for my 1999 Jeep Grand Cherokee, and I noticed that a lot of people seem to be having problems with these. Just thought I'd mention that I found a great deal on a brand new one at a site called :)

OK, if this motor is totally dead and, it will not operate under any circumstances, this will confirm motor failure. normally, if the switch is faulty, you would get some uncontrolled action form the motor. it would blow at the highest level all the time but, if its totally dead, you will need to replace the blower motor in this case for sure.

    wow, very interesting. they normally don't burn out like that. they usually keep the high side and blow the low side. I'd like to see a picture of the switch plug if possible.

SOURCE: Jeep Grand Cherokee 2001 blower fan resistor replacement

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.

2000 jeep grand cherokee, only blow out a little air even when the blower on hi,,you have to put your hand next to the vent to feel the air

you may have had something fall down into the defrost vent and it has worked its way down and is blocking the air flow thats trying to come out the vents,near the blower motor.also does it sound like the blower motor is spinning on high speed or at a lower speed,you could have a slow turning blower motor.

No heat unless car is moving

Do you hear a change in noise when you change the fan speeds? Its more than likely a blower motor thats inoperative. Start by seeing if ANY of the speeds work. If none of them work, its probably not the switch or the resistor. Try jumping battery voltage to the blower motor and see if it turns on. If not then you need a blower motor. Hope this helps

We own a 2001 Jeep Grand Cherokee and the a/c and heat are not blowing at all, only the defrost works on low,

have the blower motor resistor checked it may be bad causing air not to blow, you will get a little heat at defrost because heat rises and thats the high point, the blower motor is not working check that resistor.

The resistor is screwed into the heater housing under the dash on the pass. side. If you have auto temp then the part is expensive. You should be able to see red and black wires going to the resistor. If the resistor is bad it usually has high speed only. Jiggle the wires at the resistor and see if the motor comes on. See if you have power at the red wire with the blower on.

96 Jeep Grand Cherokee will not blow out hot air

It's possible you are not getting enough coolant flow to your heater core. Try pulling the hoses off the core, blowing it out with air compressor, fill with water and blow out again. Try this about five times and see what happens. Alot of times these cores will plug up or have restricted flow. They will blow warm at low speed but it won't flow enough hot coolant through to stay hot on high blower speed.
