There is an updated resistor/connector package. Very expensive from GM, try your local NAPA or other parts supplier for a replacement

there should be a resistor for the interior fan motor,not sure of location,probably near fan motor,possibly blown.have you checked all fuses?

You should be replacing the blower motor with the resistors. If your buying the parts from the dealer an experienced parts person will insist you replace both at the same time. The blower motor is usually what burns out the resistors.

WELL YOU HAVE TO USE A VOLT METER CONNECT ONE VOLT METER WIRES TO GOOD GROUND AND THE OTHER VOLT METER WIRES GOES TO EACH SWITCH SPEED.IF VOLT METER GET VOLTAGE A 1 OR 2 CONTROL SPEED RESISTOR BAD.IF RESISTOR BAD YOU WILL GET 1 OR 2 BLOWER MOTOR SPEEDS.IF BLOWER MOTOR WORKING.CHECK THE AC AND HEATER CONTROL SWITCH FUSE OR CHECK BLOWER MOTOR FUSE AND RELAY.IF ALL GOOD SO FAR CONTROL SWITCH ITSELF COULD BE FAULTY.

Can you possibly post a picture of this?This sounds like something that was added for add on equipment. As far as the blower motor goes try wiggling the plug that is connected to the blower motor or tapping on the bottom of the blower motor to see if it will turn on.The most common issues with an inoperable blower motor is the pigtail plug or the blower motor itself.Were you able to verify that the fuse is ok?The 2 wires that go to the blower motor should an orange and a black one. I'm going to post a the wiring diagram for the manual HVAC system.If this is automatic please let me know the diagram is a little different for the Auto HVAC.
Please feel free to ask any questions.Will try and assist you best as possible.

The 2005 Spectra heating system comprises 4 main components and its associated wiring.
1. Blower Relay- supplies power to the blower motor when the key is in the on position
2. Blower motor- Located in the right side dashboard area near the passengers right foot. ( photo attached)
3. Resistor- located on the ground side of the circuit to control speeds 1 thru 3. Note" High speed bypasses this component.
4. A/C Control Module- This is the control pad in the dashboard with the blower speed controls.
The easiest way to diagnose this circuit is to split the circuit in half to determine if you have a power supply problem, ground control problem or a failed component. From your concern I am going to assume that none of the speeds work. If some of the speeds work let me know which ones and I will revise the diagnosis tree I made for you.
Key state for all tests is Key on/Engine off. Heater on and blower setting between 1 and 4.
Step 1. Verify the 30Amp blower fuse in the underhood fuse box has power and is not "Blown.
Step 2. Locate the blower motor by removing the lower kick panel on the passenger side dashboard and glove box. You will need a Phillips head screwdriver.
Step 3. Disconnect the two pin connector at the blower Connector G-02 in the attached photo. The red and blue wire is the power supply wire to the motor so with the key on/engine off check for power with a test light or volt meter. Spec: Battery Voltage. If good proceed to step 4. If no power proceed to step
Step 3.a.- the blower relay above the blower (connector G-06) and verify you have power leaving the relay. This is the red and blue wire ( Pin 4) I attached a photo of the connector to help locate the correct wire. If you have power at this pin the relay is working and you have an open between the relay and the blower motor. If you do not have power at this pin proceed to step 3.b. Verify that the relay clicks when you disconnect it from the harness and plug it back in. If it "clicks" and you have no power at pin 4 you have a bad relay. If it does not click you will need to check the power supplies to the relay. These are pins 3 (blue wire) and Pin 5 (Red wire). Be careful to check the correct blue wire as the other blue is the ground for the relay. (Pin 1). If you do not have power at either wire you have an open in the harness and further diagnosis will be needed. If you do have power at these wires then check the remaining blue wire for a ground. If you do not have a ground you may have a bad control module. To check this remove the plastic cover around the control head and radio and remove the control head from its mounting but leave plugged in to the harness. Check the white and blue wire in pin 21 of the large connector. It is located 3 pins in from the bottom left of the connector. (See attached photo). If you do not have a ground then you have a bad control module. To verify this you can ground this wire with a test light or fused wire and see if the relay "Clicks". If you do have a ground at this pin then you have an open between the relay and control head.
Step 4. - Ground check- Go to the blower motor connector and check the green and red ground wire (Pin 2) for a ground with the blower switch set to 4. This bypasses the resistor easing diagnosis. If you have a ground then the blower motor is at fault. If you do not have a ground proceed to step 5.
Step 5. Access the control head large connector. Leaving it plugged into the control head check pin 23 (Yellow black wire in the lower left corner of the connector) and verify you have a ground. If you do not have a ground you have a faulty control module. If you do have a ground you have an open between the blower motor and the control head requiring further diagnosis.
