Go to HVAC System Check

1. Disconnect the RH electric actuator connector.
2. Turn the ignition switch to the ON position.
3. Use a DMM to measure the voltage between terminal 5 of the RH electric actuator connector and ground.

Is the voltage within the specified range?

10.0-14.0V

Go to Step 4

Go to Step 3

Check the HVAC MiniFuse® #18 for an open circuit.

Is the fuse open?

1. Reconnect all of the components back to their respective connectors.
2. Connect the scan tool to the diagnostic link connector.
3. Turn the ignition switch to the ON position.
4. Select HVAC readout parameters on the scan tool.
5. Rotate the RH side temperature control knob between full hot and full cold.
6. Check for the RH MIX MTR POSITION REQUEST and the RH MIX MTR POSITION FEEDBACK signal on the scan tool.

Does the HVAC Control Assembly send a change in position request to the RH actuator but the RH actuator sends no feedback response to the HVAC control head?
