Question about 2004 Saturn ION

1 Answer

HVAC Blower stopped working

My fan/blower stopped working recently. I checked/replaced the 7.5a HVAC fuse on the inside fuse box and also replaced the RUN relay but neither solved the problem. Are there other fuses/relays that I need to consider?

    I did end up replacing that 30a fuse before reading this and it didn't appear to be the solution. But then I disconnected the wire to the blower unit under the dash to check it with a multimeter. When I reconnected the harness the blower worked. I'm not sure what happened (the harness wasn't loose), but with all of the suspect fuses/relays replaced it is now working.

The fuse you replaced powers the hvac control. The run relay is powered by a 30amp fuse in the fuse box near the battery.
Is the relay getting power from that 30amp fuse ?

SOURCE: Blower motor not working at all.

It could be the control head in the dash, or a bad wire. If you can pull the control head out of the dash and check the connection for the wiring harness, otherwise start under the hood and start checking the wiring for corrosion or broken wires.

SOURCE: cooling fan wont run

Are you getting a check engine lite? It could be the coolant temperature sensor that signals the computer to run the fan. Good Luck Darrell S

2003 trailblazer blower not working


Are you saying the blower motor would run intermittently and then just stopped working? My first thought is faulty blower motor, I've seen faulty blower motors that would run intermittently. Any motor that uses brushes, you can tap on the motor to see if it will start working, that is a sign of bad motor brushes, replace the blower motor. There could be other issues?
Did you check the blower fuse, not only check the fuse, check the fuse circuit for voltage, use a test light. Check for applicable hvac trouble codes. With hvac on, check for voltage and ground at blower motor wiring connector, if both are good and no blower action, suspect the blower motor.

The fan stopped working and I have no heat. What can be the cause?


Only 4 items in fan circuit I think; Fan motor, ballast speed resistor, switch and fuse. If you can access the single wire connected directly to the motor, you can use a jumper wire to batt + to check motor.

How do i replace the fan motor and where is it located?


wow, 3 fans in car and we get to guess,why.?
first what are you doing.? (guess,i want cab heat to blow?)
parked key off?
hot engine wanting heat from HVAC vents
? what?
or under hood and radiator fans are dead but overheated.

HVAC is a blower fan,or blower, the fuse is called blow.
does blower sound ok on high???? SouND?
if yes (if no controls are bad)
is air flow weak. yes. that is dampers failing
both the blower and dampers and heater core are in the center
tor right(usa) of dash in hugh black box.
first check fuses
then scan the car. yes, you must scan it see HVAC errors
or its all just a waste of time..

some models have filter and packed up ,my block air flow
some have it others dont,. not fun finding it.
most are behind glove box (after removal)

My bmw 318 is blower fan not working


Blown Fuse
  • Usually the first thing to inspect when the blower fan stops working is the fuses to see if any are blown. Locate the 10A cluster fuse or the 25A HVAC fuse in your car manual, and examine them to determine if they need replacing. The car owner's manual will tell you where to find the fuses that are connected to the heat and/or air conditioning. On the interior fuse panel of the car, a 30 amp fuse is labeled "Heater" or "HVAC."

Bad Blower MotorIf the fan only works on setting number 3 or 4, or just on the highest setting, it is most likely that your blower motor is failing and is about to die. Use a voltmeter to test the amount of voltage at the blower motor connector with your ignition on and AC running. If it reads 12V, the motor needs replacing.Automatic Climate Control SystemAnother thing that causes the blower fan to malfunction is the Automatic Climate Control System (ACCS). If the ACCS's settings are off, it may cause the fan to stop working. If it is the climate control on the car, typically it is a bad thermostat or electrical circuit that is the culprit.
hope this helps, James Booth

Hi, I have a 2007 suzuki grand vitara and recently the blower stop working now i have no air or heat. help!!


Look first for the fuse of the blower unit in the main fuse box. replace, if this blows off again the blower fan is faulty.
However if the fuse is intact then you must check the blower switch on the dash for poor contact.
replace as required.

MY HVAC fan stopped blowing. Checked all the


Check the blower motor speed control resistor pack is ok.
(The resistor pack is usually located in the blower fan ducting in the air flow).
Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen.
Check operation/replace any blower motor control relay,
Check the blower motor will run if +12v directly applied to the blower motor.
Check operation of the blower motor speed control switch is ok.
