Part II - Cooling Fan Operation Should be Checked After Installation of the New Relay Using the Following Procedure:
1. Engine should be cool enough that engine cooling fan is not running. (Engine cooling fan will operate if the engine temperature switch senses coolant at or above 110~ C. (230~ F.).
2. Ground under-dash diagnostic connector by jumping TEST terminal B to GROUND terminal A.
3. Turn ignition switch to "ON" position only. DO NOT START ENGINE.
4. Operate the air control (upper) lever of the A/C control. Engine cooling fan should be operating when lever is in the A/C positions of "MAX," "NORM," or "BI-LEVEL." (The engine cooling fan will also operate in the "DEFROST" position on 1982-83 Cutlass Ciera and Omega models that include relay part number 14047112, added for engine cooling fan operation in July 1983 Service Guild, page 77, and October 1983, page 6).
