A/C blower question

I have an 03 Grand Cherokee Overland with an A/C blower problem. The system is dual zoned and the high speed fan setting shuts the system down. From low setting to mid will work all day long but moving it from mid to high will shut it down. What would cause this problem?

Thanks for any help you can provide.

Fan motor not working on 2006 Jeep Grand Cherokee.


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.

The heater shut off and won't turn back on. I checked the fuses and they are good and I checked the blower fan and it works too so I'm out of ideas on what to check.


check for voltage at blower motor plug, if no power possible blower motor resistor, a lot of times when resistor burnes out only high speed works and others burn out only one speed.

Air/fan/heat only works on high in 2005 Jeep Grand Cherokee, or it will start again if I open and slam shut my glove compartment.


Check the blower motor speed dropping resistor pack and it's connections. It is located in the ducting airflow of the blower motor.

Heater fan will not shut off runs all the time on high speed. 03 dodge grand caravan


Sounds like resistor is faulty. I believe on that vehicle, look up under dash behind glove box, and you should see blower & the harness that runs from it to a resistor attached to housing/duct. Pull connector off to stop blower. Replace resistor.

Heat/AC Blower fan speed only works on High


Alot of people have the same problem with the fan switch and blown bulbs. There really is no fix for this. Jeep really screwed up when designing the heater control assembly. The cheapest solution is to buy another unit off Ebay. Can always go to the dealer but be ready to PAY for there mistakes.

2005 jeep grand cherokee 4.7 Ac fan lost the 3 lower settings, only the high setting still worked. For a while the lower fan settings would just come on, and then go out again. The high fan setting...


Well, the blower resistor handles the lower speeds and the hi-blower relay handles the hi speed only. if the fan still works on the lower speeds then the resistor is bad. if the fan doesn't work at all then your motor has failed and or burn't the relay out also. if you can get your blower to start by hitting the kick panel above the pass. side foot area then the motor is bad. if you are handy enough to drop the kick panel and access the motor then check the connections at the motor. Then wack the motor and see if it comes on then. you will most likely find the problem if you follow those simple rules above. Good luck.
