Question about 2004 Chevrolet Malibu
Sometimes the fan speed switch (for heat and a/c) works just fine and more often than not I get nothing. recently started
Sounds like its the blower motor resistor is bad, its up by your blower motor, its where the wire for the blower motor comes from, also I have seen the wire and connector melted on some of these to

SOURCE: My heater blower stopped working
The blower motor, as you have probably seen, is under the dash on the passengers side. While in Park with the parking brake applied:
Turn the Key On with fan blower set to High. Locate the blower motor and wiggle the electrical connector. If this brings the blower motor to life, a new blower motor is needed. This, if applicable, is a common failure that matches your symptoms. The new blower is simple to replace, although it is never fun working under the dash.
If you have a 12 volt test light or DVOM (multimeter) you can check for power at the electrical connector. You should have battery voltage (12+) with the blower set on high. Always use a known good ground when testing for power. If you have power (key on, set to high) and no blower operation the blower motor needs replacing.
The resistor you replaced is a very common failure on these.
Give me an update.

SOURCE: Blower motor or resistor?
If it was the motor that went out then it would not blow at all. The resistor is the culprit that starts killing off speeds. It should be about $25 to $30 at an aftermarket store like autozone or advanced auto parts.

SOURCE: blower fan only works on high
If it is working at all then the relay and fuse is good and the problem is either the little vacuum hose on the back of the control switch panel or the panel itself.

SOURCE: Blower motor or resistor?
Yes its the blower motor resistor.
More then likley theres some trash or something in it, or possibly the motor itself is on it's way out. There not that bad to pull out of that body car, just pull it out and see what you can see.
The blower motor is under the glove compartment
You can replace the resistor on your own. Please find a detailed diagram which would guide you to do it.

You are going to have to make a connector for your resistor to fit into the adapater under the dash. the new resistor doesnt reach the terminals on the connector. Even though it clips in place it doesnt reach. I took a piece of small soldier and put in the connector then plugged it in and it worked just fine. When you unplug the relay it will not work in any speed.
