A/C FAN SWITCH WORKS ONLY ON THE HIGHEST

2004 Dodge Dakota

Air Conditioning problem
2004 Dodge Dakota V8 Two Wheel Drive Automatic 48500 miles

What could be wrong? When turning on the Air conditioning, the fan switch needs to be set to its highest level for it to start blowing cold air. If turned one notch lower, it cuts the blower off and the cold air too.

I think its the fan switch thats defective. If I am wrong, could you give me diagnosis or what it could be before I take it in for fixing.

Thanks

Most likely the blower resistor is bad. Located behind glove box just down from blower wire connector held on by couple screws. Put test light on it move fan switch through the speeds if you get volts then resistor is bad.
Good luck
