KF41 - Check Fan Circuits For Continuity

CHECK POWER-TO-FAN, FAN GROUND AND INTERNAL FAN CIRCUITS FOR CONTINUITY.

- Key "OFF".

- Low Fan Control (LFC) and High Fan Control (HFC) relays disconnected.

- Measure resistance between the battery negative post and Power-to-Fan circuit at both the LFC and HFC relays.

- Are both resistances less than 10 ohms?

Yes -- Go to KF42. KF42 - Check Ground Circuit to LFC Relay

No -- Go to KF46. KF46 - Check Continuity Between Fan and LFC/HFC Relay
