'07 TL-S keeps blowing radiator fan when warm
Having issues with radiator fan blowing fuses when reaching normal temp and only condenser fan stays running. But if car is first started when cold and ac is turned on both fans work find. It only blows the fuses when car is warmed up and both fan suppose to come on and cool the engine down... I changed relays, new radiator fan and no luck.. Is there anybody with the same problems or have an wiring diagrams for the cooling fan circuits and it would be a big help... thanks

Radiator Fan Relays and Temperature Sensor
There are two fan relays, the Fan Control Relay and the Radiator Fan Relay, and an Engine Coolant Temperature Sensor (ECT).
The Radiator Fan relay in in the Underhood Fuse/Relay Box in the front of the box. It's the relay on the driver's side. The Fan Control Relay is in the Multi-Relay Box which sits next to the Fuse/Relay Box. If you haven't replaced both relays, may the one you didn't replace is causing the problem.
The ECT is probably not the problem as it sends a signal to the ECM to turn on the fan.
