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
