* Blower Motor Resistor: This is the most common culprit. The resistor controls the different fan speeds. If it fails, the blower might not work at all, or only work on high speed (if at all). It's a relatively inexpensive part and usually located somewhere accessible under the dash. A quick YouTube search for "2000 Ford Contour blower motor resistor replacement" will show you where it is and how to replace it.
* Blower Motor: The motor itself could have failed. This is less common than a bad resistor, but possible. Testing the motor requires more access and some electrical knowledge to check voltage at the motor itself.
* Wiring/Connections: A broken wire, corroded connection, or loose connector somewhere in the circuit can interrupt power to the blower motor. Check all connections to the blower motor, resistor, and the fuse itself. Look for any obvious damage to the wiring harness.
* Switch/Control Panel: The switch that controls the fan speed could be faulty. This is less likely, as a complete failure is less common than issues with the resistor, but still possible.
* Ground Issue: A poor ground connection can prevent the blower motor from receiving the necessary power. Check the ground connections related to the blower motor and its circuit.
Troubleshooting Steps:
1. Check all connections: Start with the simplest and cheapest fix first. Visually inspect all wiring and connectors related to the blower motor, resistor, and the control switch. Look for loose connections, broken wires, corrosion, or any signs of damage.
2. Locate and Inspect the Blower Motor Resistor: This is your next best bet. Find its location (YouTube search is helpful here), and visually inspect it for any obvious damage. You might even be able to test it with a multimeter if you're comfortable with basic electrical testing.
3. Test the Blower Motor (Advanced): This requires accessing the blower motor (often under the dash) and using a multimeter to check for voltage at the motor's terminals. This is more involved and may require some automotive electrical knowledge. If you're not comfortable with this, it's best to take it to a mechanic.
4. Check the Control Switch (Least Likely): Testing this usually requires accessing it in the dash and using a multimeter. It's usually harder to diagnose than a resistor or motor.
Recommendation: Start with visually inspecting all connections and then focusing on the blower motor resistor. If those checks don't reveal the problem, you may need to seek professional help from a mechanic or an auto electrician. Replacing the resistor is usually a relatively straightforward DIY repair if you're mechanically inclined. Remember safety first – disconnect the battery negative terminal before working on any electrical components.
