    same thing

    I have the exact same problem with my daughters 2003 Ion. The motor was working fine on all speeds and then one day it just started running slow on setting 4 and will not run on 1, 2, & 3 or so slow you can't hear it running. I replaced the blower motor resistor and still the same result. I measured the voltage being supplied to motor, 0 volts on setting 1, 2, & 3. 12 volts on setting 4. The motor speed on setting 4 with 12 volts supplied is about what you would expect from setting 1. That kind of points to the motor being bad. But if the motor was bad though I should still have some lower voltages supplied to the motor from settings 1, 2, & 3 which I don't have. I am stumped. Any help would be appreciated.

    Same problem with my 2001 LW300. I replaced the fan speed selector switch and that fixed it. The previous owner (my father-in-law) said he had to replace it as well before we got it.

    I had the same issue last year with my 2003 Ion. I had bought an extended warranty so it was still covered, I took it to the dealer and they said the HVAC control unit was bad, which basically meant the knob you turn to control the air flow was busted. Mine only worked normally on the highest setting and I got nothing at all from the lower ones. They replaced that control unit and they also replaced the blower motor after I complained about a chirping sound coming from it, which is a known issue with Ion blower motors wearing out. Everything works fine now.



    I also had a similar problem with my previous car, a 2001 Chevy Malibu, and it just turned out to be a little cube relay plug located in the fuse box that had burned out.



    Hope this info helps.

Lower settings as far as speeds for your blower motor go through a resister block to reduce the voltage your blower motor receives to make it turn slower. If it turns slow on high you would have to check the voltage at the blower motor, should be the same voltage that would be at the battery. There could also be material in the blower motor fan like things a mouse could have put there. Causes the fan to spin slower and also blocks the fins from pushing air. Any strange noises would be heard unless you have had the prob since you owned it and could not detect any changes. It could be even full of stuff and still
be in balance. but it could be a few other things.

    Blower motor may be bad as long as you have a good ground to the motor.But you have to know if the switch is on the power side or the ground side of the circuit. You could run power and ground to the motor direct and see if it spins fast. if you reverse the polarity it will spin backwards no damage will be caused. Best way to see if the motor is drawing too much would be to put a amp gauge in series in the curcuit when you wire it direct. Should draw around 25-35 amps
    you would have to use an older anolog (needle type gauge).

I've found out exactly what is wrong with the issue of speeds 1-2-3 not working, and speed 4 acts like low speed.
I did all the usual troubleshooting of the blower otor, resistor pack, fuses, and relay, all were fine, and narrowed it down to the switch.
I fixed the problem by eventually pulling out the HVAC control panel, and implementing the following.
[B][U]Instructions on how to fix a 2003 Saturn blower control [/U][/B]
Find a safe place on a clean bench so you don't loose any parts.
1. Leave the knob attached on the front of the panel so the shaft of the switch does not fall out. It is holding springs, a plastic detent, and a steel contact BB in place, on the inside of the switch. You shouldn't have to remove the shaft. If you do, remember the steel BB goes on the spring on the outside, or larger diameter circle, and the plastic detent goes on the spring on the inner diameter circle. The steel ball is an electrical connection, and the plastic piece is for the detent positions.
2. Remove the 2 screws holding the blower switch in from the back of the panel. Orient the panel face down, and gently pry the 3 tabs open holding the back of the switch to the main control housing.
3. Pull the back of the switch apart slowly, there is a spring and a copper contact plate that will pop up when the switch back is pulled off. Note the position of the coper plate and spring.
4. If the 2 bumps on the contact plate appear clean and have dielectric grease on it, just leave it unless you have some more grease and want to clean the copper contacts.
5. On the end of the main shaft that sticks up inside the switch housing, there are 2 tabs or keys on the end. It is a 2 level double key. If these are broken or worn down so they don't grab the round copper contact plate , YOUR SCREWD :upset:, and need another HVAC Fan Control assembly or a good shaft out of another bad unit.
6. If it is still good you should be able to reinstall the spring and copper plate. With the bumps of the plate facing out towards the inside of the back of the the switch cover, and the spring on the end of the shaft, place the copper plate onto the keyed shaft while compressing the spring (there's only one way it will go on the larger first level key).
That is the first level keying, push the plate a little further till it goes past the second level of keying and turn the plate 90 degrees (I think it was counter clockwise, if not turn it 90 degrees clockwise). Start releasing the copper plate and it will fall onto the smaller set of keys, and be held in place by the larger first level keys. There is only one way the second level keying will go, because of the different sizes of the two tabs.
7. The spring will be compressed, and the copper plate should feel firmly in place, and rotate with the knob on the front of the shaft. Hopefully it should stay put.
8. Now snap the switch back into place and install the 2 screws. It should be ready to test.
Hopefully this works for you. I just did this repair and have no idea how long it will stay in place. However if the keying was in good shape, and you don't go spinning the dial wildly with great force:dizzy:, hopefully it will last awhile.
Regards,
Willie The Wizard

    I forgot to mention that the reason for the porblem was that the round copper contact plate had somehow got off the key, and slipped off the end of the keyed shaft.

    Hi Willie, we're having this problem with my 03 ion and are wondering if you have to get right in the dash? how do you reach the HVAC? where is it located etc. thank you!

2008 Ford Edge ac runs only sometimes.... If I hit under the dashboard it will turn on but only blows out a little cold air on the highest setting. If I open the glove box I heat tons of air blowing. I was...


It could be the blower motor resistor or even the blower motor. If you hear the air blowing with the glove box open but, none can be felt, check the cabin air filter. This filter can become clogged with leaves and debris that enter the HVAC box. The filter is located underneath the dash near the blower motor. The reason for some air flow after you hit the dash is it must be clogged and it clears enough to allow for the small amount of air to pass.

Heat or AC come on but fan will not blow.....


I would say either the blower motor is not running, or the blend door is not opening to let the air thru the system.
Someone would need to verify the blower motor is running then check for a dirty cabin air filter or a stuck blend door.

Air does not blow


The car normally blows air through the blower however the controls and settings of the speed of the blower are controlled by the blower motor resistor. The resistor controls the speed of the blower fan. If your blower still works on the highest setting then the blower itself is still in working order. If you are not getting any air at all, even on the highest setting, then chances are the blower has gone bad, blown fuse or open wire. If this does not help please give us more information to work with.

2003 SATURN ION CHIRPING ON BLOWER MOTOR , has a high pitch when the air is turned on seems to be coming from the passenger side.


Sounds like something in the blower motor fan (also called the squirrel cage) Sometimes mice bring things into this for a nest.

03ion fan only blows on low when turn on reguardless of setting


You have either a bad resistor pack or a bad switch. Replacement is the only solution for each.

Air conditioning blowing only highest setting but HOT air


Sounds like your freon has leaked out and your heater blower resistor is burned out. Deffinitly take this to the dealer.
