I have a 1996 jeep grand Cherokee, and my blower motor has quit. What could the problem be?? I checked the fuses and they all are in good condition.

I had this same thing happen to me in a Buick Lesabre. It ended up being the blower relay. There was 2 relays for the blower motor. One was called the high blower relay which controlled the high speed. The one that fixed the problem was the blower relay that powered up all the other speeds. I hope this helps.

On a 94 Jeep Grand Cherokee check fuse 17 should be a seven and a half amp fuse if the fuse is good go under the hood to your power distribution center look for the air conditioning relay swap it with one of the other ones several of those are Universal fit see if it works then

So you're getting heat, but the blower fan itself is not working (hot air comes from open vents, but not "forcefully blown in" from the fan? Were you hearing any squealing noises when the fan was on, before it quit working? If so, your fan motor is probably dead. It could also be the fan switch, or a fuse or relay. in the circuit.

check fuse at driverside below steering wheel at kick panel and also there is a fuse in the fusebox below bonnet near battery.

check for battery voltage and good ground at fan electrical connector. If both are ok then fan motor is bad.

the blower motor resistor is bad replace it and it will work good as new the resistor is located in the same heater box as the blower motor mounted on the outside of the heater box follow the wirring from the blower motor to find it or just simply buy the part and match it up

In the Power Distribution Center (underhood) check the Maxi Fuses, position A5.

More details can find in the ZJ Service Manual Secc-8W-Wiring-Diagrams (page 9).

Hope helps with this (remember rated this help) Good luck.

Check all fuses. If o/k check for 12 volts at the blower motor. If no power at blower the system has to be traced to find where the power quits. Hope this heps.

Blower motor is likely bad if it doesn't work on any speed, if it works on only one speed then there is a resistor located by the blower motor that is bad each item should run around $30 at local parts store
