Heater blower doesn't work - 2002 Jeep Grand Cherokee

2002 Jeep GC. with auto temp control. Heater blower stopped - replaced connector to blower control module. Also have new module. Blower motor works with direct connection. Had some questions about wire order going to connector. A - black ground B - red hot C has smaller wire - original color is yellow and brown. My brother thought the small wire was in the middle (B) of the connector when we disassembled. Diagram has red-hot in "B" slot. Put everything together and blower doesn't work. Ignition was on.

SOURCE: 1997 Jeep Cherokee - Blower motor stopped working.

Check the relevant fuses with a test-light or VOM, don't just "eyeball" them as they often break at the very end. Then check the heater/A/C relays on the electrical panel. The heat/cool is controlled by a stepper motor which opens and closes the air "mixing box", but it won't work with a bad relay. If all of those check-out, you need a OBDII code reader to check the "engine" computer, as it controls the electrical modules. Also check the fusable links going to the electrical panel, and the cable from the battery to the panel. The cable may be corroded in-two and you'll never see it, so no juice to the panel, no juice to the heat/AC system. (I had a Dakota do that.) PS: Double check the grounds that they aren't corroded. Learned about that from a BSA Gold Star production racer.....

I had the same issue. It turned out that one of the wires had burned out and therefore the connection would not hold. The dealership had to replace the wire and the connection point. They said that it is a manufacturer problem, however, generally it takes about four years to fail...so they don't have to replace it.

SOURCE: 2002 Jeep with a melted

it is very common for the heater resistor to produce heat and create the problem you are stating. It is caused from poor connections and then in turn create more heat and melt connector. The fix is to replace the connector like your stating....BUT most important, make sure connections get soldiered. Also make note, when plugging in, make sure connection is fully seated. Check for any damage to matting pins, signs of black must be cleaned, using small piece of sand paper or small file. If you have, apply some dielectric grease to pins prior to installing, it also helps reduce heat and keeps out moisture.

hope this helps, good luck and feel free to ask and more questions but responding to this thread

hello what i would do is try turnning the blower switch to a slower or faster speed you might have a bad blower speed switch also try tapping the switch knob if it comes back on replace the switch if it doesnt then simply turn the switch on and try to manipulate the connector plug at the blower motor mabye bad electrical connection if it turns on and off you may have to replace terminal ends at connector at blower motor. also you could use a test ligt at connector to check for power if it will light a test light it should run.

The heater stop working and i dont know what it could be? its a jeep gran cheroke 2000


If you're getting air blowing, but it's just cold, and you have the auto temp controls, you probably have broken blend doors. Do a search for "Jeep Blend Doors" and I'm sure You'll find pleanty of info. Also google "Heater Treater" for a fix.

If your not getting any air, you may have a burned out connection going to the blower control module. This happened to me. Under the dash on the passenger side, next to the door, you'll see the blower motor. Trace the power lines coming out of it, and trace them back to the control module. Unscrew the two screws from the control module and drop it down. Now unplug the motor power lines from the controller and look for a melted connector. This is a known issue with Jeep. They sell a repair kit that you use to wire in new, thicker gage wires into a new connector. Check out this site for more info: http://www.wjjeeps.com/blower_motor.htm

1995 Jeep Grand Cherokee Climate Control issues


. Open the gloves compartment (gc) . remove 2 rubber pieces that keep the gc on its place (both sides) . look to the left side. there is a connector with a few thin colored hoses. This thin hoses are there to control the operation of the blend air door. It is vacuum operated. . now follow the thinnest hose, probably it is green, all the way to the right. It connects in a sort of vacuum valve that control the position of the blend air door. make sure it is firmly attached to it. also check that hoses connector to ensure that all thin hoses are well connected. . OK! start the motor and operate the knob on the panel. It should work fine now.

Heating and air conditioning


The blower motor works on high setting ONLY when the blower resistor is bad. The blower motor resistor is held in place with 2 screws and attached into the heater housing under the right side of the dashboard. You can identify the resistor by the big wires that are connected to the connector. If this heating/cooling system is the auto temp type, the part is a bit high on the price.
