    The blower in my 97 isn't working either and I understand that the wiring harness is faulty. The mechanic says I have to buy the whole mechanism to get the harness, and the part will run over 200 bucks.

    Does that seem accurate?

I have a 93 Jeep Cherokee. The blower motor for A/C / heat has stopped working and I was told it could be either a relay or a blower motor resistor. How do I determine which part I would need ?


You will have to test those parts to see which one is bad......either that or replace both parts, one at a time, and hope you get the right on, on the first try. Also, when the blower resistor goes bad, it usually still works on the highest speed but not any others.
BTW, has anyone tested the actual fan blower motor, to see if IT might be bad?

Where is the blower motor relay located on a 97 grand cherokee


The resistor is to the left of the blower, it is very hard to get to but not impossible.

Good luck.

I have a "92" cherokee. The heater blower moter


It could be the control switch, but it is a task to replace. The easiest low dollar solution is the relay. Foe a couple of dollars, you can rule out the switch. Otherwise, if the relay does not work and a diagnostic approach was conclusive on the circuit, then the switch is suspect.

The fan will not come on to blow the heat or anything on my 1997 jeep grand cherokee. PLEASE HELP


Go under the dash on the passengers side.The blower motor and blower motor resistor are located under there.With the switch on just tap the blower slightly and if it goes on then replace the blower motor.If not then follow the wires that go to the resistor and check the resistor.They like to heat up and melt the connectors.So you might have to replace the resistor and the connectors which you can get from the dealership parts department.Make sure you have checked the fuses first.let me know if you have any questions.Good luck.

95 jeep Cherokee heater wont work but rear window defrost still works need help please


Check the blower motor fro good connection, power and ground. Hot wire it to the battery and see if it runs. Check the blower fuse, relay, switch and resistor pack.
blower and rear defrost circuits are totally unrelated.

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.....

Heater and overdrive button as well as heated seats quit working


Your heater problem could be a blower motor resistor if the motor does not work at all. If the blower does work then the problem could be a bad heater valve. I assume that the 30 amp blower fuse is good. The seats and overdrive light have no connection with the blower. Does the heated seat light come on? Do you have automatic temp control.
