Replaced resistor on 09 Malibu

Is this diagram correct for what you have? Did you check for voltage at the fuses? Use a test light. My database showed two hvac diagrams for your vehicle. You see the wire colors on top of resister, that is for first speed--2nd--3rd, you can check for voltage on those wires with test light, key on--hvac on, just pick the speed and proper color wire. Be sure to check fuses in bcm.
