G35 2007 Overheating in traffic

[jsemelgar]

My radiator fans don't come on. The two fuses near the battery are good. When I ohm the radiator fan motors they show an open line on Black & Green wires, but show micro ohms on Blue & Yellow. I ran power straight from the battery to the fans but they did not turn. I don't see a fan relay, if there is one on this car. The parts guy at the dealership told me over the phone that it sounded like the fan motors are bad. I also disconnected the wiring harness at the fans, turned the ignition to ON (did not start motor) and checked for power going to the fan. Unfortunately (if I checked it wrong) I did not get power coming from the wiring to the fan. I don't see any fan control module on fan motors and I see no fan relay.

Any suggestions would be appreciated. I think you in advance for your replies. Jim.

Welcome to NICO!

Sorry to hear about the issue your having. It does sound like the fan motors...but not for sure. Check out the FSM (link in my sig) for detailed wiring diagrams and other troubleshooting steps.

I couldn't pull up the link for the 2007 coupe but the sedan has a relay and a fan control module

Cooling fans are controlled by cooling fan control module. For details, refer to EC-23, "Component Parts Location".

If you are still under warranty take it to the dealer
If not ask for an estimate

Good luck

Hey Telco man, where did you get this manual. It looks like what I signed up for on AllDataDIY.com, only yours has so much more detail. AllDataDIY was basically useless to me. I think I'm going to cancel it. BTW, I paid $40 for a diagnosis. It's one of the fans. I see that I can order them online for around $35 each. Thank you and all for assistance.

Yes, of course, thank you Joe. I'm new to using this site and was not sure how to email a message directly to a user. Either way, thank you all that took the time to read my posting.
