Engine Overheating Testing Cooling Fans Relays Ipdm Fuse Box Finally fixed the problem with nissan 350z overheating , and cooling fans dying often , the problem was in the bad fuse box relay contacts!!!. The issue with my radiator fan: there was a short, which caused my relays to break every time they were inserted, they went through the same steps as i did with the service manual, fixed the wiring completely, and then tried it. turns out, this short also broke every ipdm i installed.
Original 2003 2010 Infiniti Nissan Cooling Fan Relay Ipdm Fuse Boxо Key points. recognize symptoms: engine overheating, poor a c, continuous fan operation, battery drain, risk of a c compressor damage. inspect for damage: check for corrosion, burnt marks, loose pins, cracked sockets in the relay. test functionality: use a multimeter, check for continuity resistance, listen for a click, inspect physically. Another common symptom is when, the fans don’t come on at all. so, if the cooling fan relay fails, it will be unable to supply power to the fans. as a result, the fans will not operate. cooling fans, that will not turn off. this is another (less common) symptom of a bad or failing cooling fan relay, but it does happen. With the engine off and cool, open the hood and locate the radiator fan. it’s typically situated near the radiator. look for any signs of damage, such as cracks or loose blades. ensure the fan is securely mounted and doesn’t wobble. check for debris or obstructions that might prevent the fan from spinning freely. 2. Step 1: locate underhood fuse relay box. visually identify the underhood fuse relay box. the box is typically located on either the driver or passenger side of the engine compartment near the fender. step 2: remove the fuse relay box cover. remove the cover from the top of the underhood fuse relay box.

Fuel pump relay: 48: 10: cooling fan relay, headlamp aiming motors, headlamp aiming switch, transmission range sensor: 49: 10: all wheel drive (awd) control unit, power steering control module, abs solenoid valve relay, abs motor relay, steering angle sensor, yaw rate side decel g sensor: 50: 10: front and rear washer system, combination switch. The cooling fan kicks in and sends air flows to the engine. the air flows will continue until the sensor or ecm informs the relay that the temperature is normal again. then, the relay returns another electric charge to the radiator to switch off the cooling fan. with this, the relay is an intermediary between the sensor ecm and the radiator fan.
