Why does my Jeep Jeep blower keep failing?
Most of the time the problem is a melted connector on the blower motor controller, but you changed that one already and would have seen the melted connector. When it fails again, i would try and wiggle a bit with the wiring on the controller and the blower motor itself. Could be a bad contact or an internally broken wire.
What happens if heater blower motor does not work?
Therefore, if major problems in the heating and air conditioning system fail, as if the power supply to the motor was completely cut off due to overheating or corrosion, the motor will simply not work, which in turn will render the entire heating and air conditioning system unusable, as no air will flow through the vehicle’s air vents. 2.
Why does my blower motor only work at slow speed?
Blower motor only working on low speed. Another common symptom of a faulty blower motor resistor is that the blower motor only works at slow-speed. This can be caused because of bad wiring between the blower motor resistor and the blower motor itself.
Can you replace the blower motor on a jeep WJ?
By the way, the link you posted on the blower motor replacement is not for the WJ. The WJ does not have any cover over the blower motor, you can see it when looking up in the footwell area. Attached page shows how it looks like, eventhough it shows it as seen from the front side, which ofcourse you can not see.
Why is my Jeep Cherokee heater not working?
What are common reasons my Jeep Cherokee has heater problems? While there are a variety of reasons your Jeep Cherokee heater is not working, the most common 3 are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor.
Why is the air blower on my Jeep not working?
I will start the Jeep and the air blows fine, then without rhyme or reason it completely stops (there is no specific duration between work/failure). Depending on the length of the trip, it may come back on again. I replaced the blower motor resistor and I thought that fixed the problem, but unfortunately it did not.
What’s the problem with my heater blower motor?
Vent the car and then everthing was working. Not going to make a 2-2/2 drive to the dealer for them to look at it and say nothing is wrong. I think that is when the motor had its first failure. The blower motor has worked for a while but never at speed like when it was new, but has now given up the ghost.
Where is the blower connector on a jeep?
The blower motor sits right next to the resistor or controller (resistor is for manual AC, controller is for automatic AC system), so the connector can be found on the blower motor itself. Since the state of the blower changes after switching ignition off/on, the problem can be inside the AC control panel.

What causes a bad or failing blower motor relay?
Blown fuses. One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse. If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current…
Where is the blower control switch on the dashboard?
The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor.
What does it mean if your blower motor is not working?
Average rating from 849 customers who received a AC is not working Inspection. The blower motor resistor is an electrical component that is a part of the vehicle’s heating and air conditioning system. It is responsible for controlling the blower motor’s fan speed.
The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor.
What are the symptoms of a bad blower motor relay?
3. Melted relay. Another more serious symptom of a problem with the blower motor relay is a burned or melted relay. Relays are exposed to high current loads and can sometimes get hot when they develop problems.
Where is the blower located on a jeep?
Since the state of the blower changes after switching ignition off/on, the problem can be inside the AC control panel. “The blower motor sits right next to the resistor or controller (resistor is for manual AC, controller is for automatic AC system), so the connector can be found on the blower motor itself. I have manual a/c.
Why does my front blower randomly stop working?
It appears that when the WIN has lost “sense” of the FOBIK, it randomly either shuts off the vehicle or turns off certain controls in the vehicle (as if the key has been removed). I will continue to post over time to confirm the fix on this.

Why is my Jeep Wrangler fan not working?
Recently the fan on my 2001 TJ stopped. It does not work on any speed or on heat or A/C. I pulled the blower motor and straight wired it to the battery. It worked. I also pulled the speed selector switch. I ohm the switch. It appeared to be ok.
Is the mode door actuator on a jeep WJ?
The blower motor is completely electrical and the mode door actuator is vacuum controlled. By the way, the link you posted on the blower motor replacement is not for the WJ. The WJ does not have any cover over the blower motor, you can see it when looking up in the footwell area.
What are the symptoms of a worn out blower motor?
One of the symptoms of a worn out blower motor is that it can intermittently produce a loud screeching noise when running. How to test a blower motor? If the blower motor doesn’t work at all, the blower motor itself must be tested first. Typically it’s done by measuring the voltage at the blower motor connector when it’s turned on.
Why are the vents on my Jeep not working?
This is typical of a vacuum leak or failure of the vacuum check valve. When you ascend the hill, you loose vacuum from the engine and the A/C vacuum controls loose suction so the vents can’t remain open. Most systems then default to defrost vents.

Why does the a / C blower motor cycle on and off?
The A/C blower motor cycling on and off is definitely the A/C system informing you of a problem. It’s identifying a fault. That fault is usually a broken blend door actuator gear on the driver or passenger side. If the blend door motor actuates past its normal travel… the A/C unit acts in this manner.
What to do when your Jeep Wrangler heater stops blowing?
A good squeeze on the connector and a push on the red tab cured all that ailed. Research as suggested above but do you also lose wiper/radio power when the blower is not working? If you do, try wiggling the ignition key to see if it will kick on.

Why is my blower motor not working properly?
Make sure your getting 12v (battery voltage) from the blower motor connector while the setting is at the highest. If there is a battery voltage, the problem would be the blower motor. IF the voltage disappears from any setting, you should check the ATC connector on the back and make sure its connected properly.
What happens if you have a bad blower motor?
The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air.
What to do if your Jeep blower fails?
If you look up in the passengers foot well, you can see the resistor and besides it the blower motor. The motor is fixed with 3 screws. Just wiggle all visible wires and see what happens. If the problem is inside the AC control panel, then there is most probably not much to do then replacing the panel.
