Question about 2000 Pontiac Grand Prix

Fan on high setting all the time, and won't quit

The fan motor is running at high speed no matter where I set it...Off, 1, 2, 3, 4, or 5. It doesn't even quit if I turn off the ignition! It's out in the garage right now with no key in it, everything else is shut down, but the fan is going full blast. I expect a dead battery by morning.

You need to replace the blower resistor/relay.

    I'm not kidding, It needs a blower resistor, It will fix it. If you don't believe me, unplug it it will stop. It is located near the firewall just ahead of the blower motor, under the dash, above the passengers feet.

Rear blower: only works on high when set on cold, won't work at all when set to heat


I would start with the rear blower motor resistor, the resistor is what controls the speed of the fan, the resistor is located in the rear heater box near the blower, you will need to remove the right rear side panel to access the heater box. start with that

Air condition and heat won't work


Check to see if you are getting voltage to the blower motor if you are the motor is bad if not check the fan speed switch. 1 2 3 or low medium high if you get voltage going to the switch but not from replace the switch if you have voltage from switch check the blower motor resistor the although with the blower resistor you commonly have a high fan speed in the max setting and the lower speed settings don't work wich would make you think 1 2 3 are not working but 4 is. That is why it is best to check all parts to make sure the part you do replace needed to be replaced

2004 jeep grand Cherokee's radiator fan won't run on high


Hi Al, I'm glad to help!

Three possible causes: (1) The high speed circuit in the radiator fan motor could be defective. (2) The high speed fan relay Could be defective. (3) It possibly may have a wiring issue. I've seen at times where you can wiggle the fan motor connector that's mounted on the fan shroud and the motor will kick on. If this is the case then replace the hole assembly which is a motor and shroud assembly. Hope this helps and have an awesome day.

04 Saturn vue compressor turns off when fan is set to 3 or 4


Does the AC get cold. The compressor should turn off as the pressures rise and fall, it doesn't run all the time, running the fan on different speeds changes the pressures in the system.

The ac is on full at all times, even when you adjust the fan hight. someone sayed i need a a/c auto amplifier. but i can't find that part


Good Evening, If I am translating this properly your fan only works on the high setting? And the other settings do not change the speed? If this is correct respond back and I will help as much as possible.

Fan on High Only


The fan motors use a set of resistors to control fan speed. The lower speeds generate more heat in the resistors and these tend to burn out. While it is possible the switch could be the issue, I would start with the resistors. It is usually a module located somewhere near the blower motor.

Note: One of the reasons these go out, is that with time the bearings on the blower motor go bad and the motor takes more power to run. If the replaced resistors fixes the problem, but then fail too soon, look at replacing the blower motor as well.

Heater fan only works on the two low settings.


if you have checked the switch as recommended, it is most likely to be the heater resistor which contols the diffrerent speeds. it is
normally fited near to the motor and is a squarish block with multiplug on it and coils like springs in the centre of it, look at the coils they may be burnt out.hope this helps

Heater blower only blows on low


This could be a few different things:

1.Check the power and ground connections on your blower motor, corrosion can cause high resistance and a slow blower speed.

2. Check your available voltage at the blower motor on the different settings. it should vary with high supplying 12volts, make sure to do this check with the blower motor still plugged in.

3. Connect the blower to a 12v power source and see if it runs at high speed.

If all else fails i would check your resistor pack, i would not suspect this because when it fails you usually just loose all speeds except for high, but it could happen.

Heater fan only works on high after replacement of heater core


It's very possible the fan motor has quit. The squealing noise is caused from motor bearing failure. As the bearings wear out or dry up the motor is harder to turn and require more current to run the motor. On lower speeds, the motor runs off a series of resistors that reduce the amount of voltage and current so the fan runs a lower speeds. If the bearings are worn, there is not enough voltage or current to turn the motor and that's probably the humming noise your hearing.
Good observation by the way.
Let me know.

The Fan speed has stop working on all setting except high/


so your fan stopped working on all settings but high....? sounds like a bad switch...i know alot of jeeps and fords have that problem....lemme know....might hafat add another car to the broken fan switch list....lol
