Do not disconnect the harness from the actuator. Remove the actuator from the water valve.
Verify that power, signal, and ground are all present at connection (2). Refer to Illustration 2.Note: If needed, then refer to the Specifications, SENR5664 publication for information about testing the HVAC electrical circuit. The information will be found in the "Testing and Adjusting" section under the title "Electric Heat Control". This information provides an explanation of the electrical circuit that is to be tested.

If there is power, ground, and signal at connection (2) and if the actuator does not move, then check for the power, signal, and ground at connector (4) .
If there is power, ground, and signal at connection (4), then go to Step 5.
Unplug the electrical connector at the actuator and then plug the connector back in. Perform this task two or three times. If the actuator begins to work due to this procedure, then use the "Repair Procedure" in order to replace the actuator. Do not throw away the faulty components. When finished with the repairs, the faulty components should be returned. Refer to Step 13 of the "Repair Procedure".Repair Procedure
Cut the harness wires that are connected to the water valve actuator connector. Refer to the top picture that is shown in Illustration 1. Ensure that each of the three wires are identified and are labeled as power, ground, and signal.
Close the valve that is located in the engine compartment that is for the coolant lines.
Loosen the hose clamps that are on the coolant lines at the water valve.
Remove the water valve, the actuator, and the electrical connector as one assembly.
New connectors must be installed on the wires that were cut. Use the crimp tool in order to attach a gold socket contact to each of the wires.
After a gold socket contact has been
