93 Jeep Grand Cherokee Blower motor problem

I have a 93 Jeep Grand Cherokee and the blower motor will not turn off. Even when the vehicle is shut-off and keys are out the blower motor stays on. Turning the controls does nothing on the dash. The only way to get blower to stop is to remove the fuse or unplug the motor from under the glove compartment. Does anyone have any idea way this is happening?

No,

But my daughter just called me and we have the exact same problem with our 93. Let me know what fixes it.

Thanks

see if someone ran a hot wire from blower to fuse block or battery. this is done to bypass a bad switch.

I will check, but I had the vehicle for about a year and this just happened one day.

My 200 Jeep does the same thing. But it does it intermittently and at times when I'm not around. By the time I get back into the jeep and try to start it the batter is usually stone dead. I have to disconnect the battery, recharge it ( hoping each time that it hasn't been destroyed by the deep discharge ) then reconnect and drive. It sucks because my dealer has supposedly fixed it twice. A year later and now it's doing it again. The 2000 jeep doesn't have a fuse or connector I can easily get to, so I have to disconnect the ground terminal from my battery every time I leave my jeep.

My 1995 Jeep Grand Cherokee started doing this last night and the blower kept running after the ignition was completely turned off. Battery was stone dead this morning. Has anyone found out the solution to this problem?

Boy, this must be the time of year for this problem to happen. The exact same thing happened to me tonite. I sure hope someone has a solution. My history up til now is; been getting a check engine light, which indicates a ground problem somewhere, but doesn't say where; then was getting a message center message that said to maintenance 4wd switch, that I have now idea what it is; then tonight the blower motor wouldn't shut off until I pulled the 40a fuse under the hood. HELP..........anyone????

Does anyone know where, and how to access the blower motor resistor? I have a 1995 Jeep Grand Cherokee Limited, and the Clinton book just shows a wiring diagram, but doesn't identify the location.

Whoopee!!! I finaly got mine fixed. There is, what the "junk yard" guy said was a relay resistor mounted on the bottom of the heater housing, next to the blower motor (easy to get to). Replaced it with a used one, now every thing pertaining to the blower fan speed & etc is working as should. I am HAPPY!!
Thanks guys for your help.

Did anyone with a 1993 find the problem with the blower motor staying on full blast. This is a car with the Climate control module...not a manual. In other words it controls the temp and the blower speed when placed in Automatic mode. I have looked for any kind of relay or module that might control this but can not find anything. Only way to shut it off is to pull the 30amp fuse from the fuse block in the engine compartment.

I have a 1995 Jeep Grand Cherokee Laredo, 2 wheel drive, 6 cylinder. My blower motor stopped working. No AC, no fan. Gets hot here in Florida real fast. It had been acting funny for a few weeks, not starting and then going on when I turned the direction knob and/or fan knob on and off. Then it quit totally. Checked fuses first. In the fuse box on side of dash next to passenger door it was fuse 17. Also checked the blower motor fuse under the hood in the long plastic box near the battery, easily accessible. Both fuses were fine. Unplugged motor and was not getting any voltage to motor as per multimeter. Then jumped the blower motor by using small alligator clips hooked to inside of light socket just to test. Motor worked fine. Next I got a blower motor resister from Advance Auto and tried while in parking lot. Didnít work so returned it. Advance takes this back which is one reason I buy parts there whenever I can. Autozone said they donít take any electrical parts back once you leave the store which is I think is a rip off. Anyway, the blower motor resister is just two screws under the blower motor housing Next I took about 8 screws off the plastic cover where the radio, climate control and ashtray are, the pulled the plastic off. 3 more screws to remove the panel with the control knobs in it. This was $300 + at Advance auto and $100 on internet (e-bay). Was figuring I would start searching junkyards. Then decided to tap the unit a few times with the end of a screwdriver and got a one second response from the blower motor. So I tightened up all the connections on all 3 controls and starting tapping the brown plastic pretty good. Was holding upside down tapping the fan switch when it started up. Tested about 10 times and continues to work fine. I had tested the wires going into the fan switch prior so I knew there was power going in. I was also able to jump the wires in the plugs that showed voltage to get a low, medium and fast fan speed out of the blower motor. However, I noticed all the air came out of the defroster, That was because with the engine off there was no vacuum to cause the air to go to other settings like legs and body. Once car was started, all worked fine. Hope this helps.

I've got the opposite problem. 1993 jeep grand cherokee, auto climate control. For a long time when the blower was on it would be very loud with a lot of clicking. Now that winter is here, it decided to never turn on. Used to be able to kick it on but not anymore.

When I turn it from off to on, I hear it trying to start. The heat would work when it did work. Wondering what the problem might be? Relay or motor?

Little rectangle box ] passanger side under dash you will have to splice some wires for new one but it does run off on speed
