If the radiator fans in your 1995 Jaguar XJ6 are running constantly, it may be due to a faulty temperature sensor or relay that is sending incorrect signals to the fans. Additionally, a malfunctioning engine control unit (ECU) or an issue with the wiring could cause the fans to operate continuously. It's also possible that the fans are stuck in the "on" position due to a short circuit. Checking these components can help diagnose and resolve the issue.
I have same...Fan Controller on front clip bad, or shorted lower radiator thermo switch, drivers side.
fan stays on when car turn of
The Radiator fan relay has probably failed. It is bolted to the lower side support next to the radiator.
The rad fan relay has failed. It is loacted on the driver side of the radiator, under the air filter box, on the frame rail.
alot of the time when the censor for the cooling fan dont work,people will hook the fans up direct.Check to see if there are wires coming from the fan to the battery.I hope that helps.Fred
There should be no problem... I have put in my car in a time of emergency... and it was fine until i could take it to the dealership...
2001 VW jetta the radiator cooling fans run all the time they run soon you turn the ignition switch on with cold engine. if the engine is hot and you turn the ignition switch off the stay on till battery goes dead.
ITS TIME CONSUMING , BUT U NEED TO REMOVE BOTTOM PANEL UNDER CAR, REMOVE TOP RADIATOR SUPPORT.. PULL RADIATOR AND COOLING FANS UP BUT BE CAREFUL...MAKE SURE YOU DISCONNECT ALL THE SENSORS AROUND THE FANS. ITS A PRETTY EASY THING TO DO, IT JUST TAKES SOME TIME AND PATIENCE. DONT FORGET TO REMOVE THE HOSES TOP AND BOTTOM.bj
Hi, There is no radiator fan "sensor" for this vehicle. The fans are controlled by the Powertrain Control Module (PCM). The basic concept is that the PCM uses a temperature sensor to measure the engine coolant and will turn the fans on and off at the appropriate time and speed. There are certain conditions where the radiator fans will turn ON (at high speed) all the time, but that normally only happens when there are other problems in the system. If you want to find out more details about how the systems works, use the "related link" I have included. Good Luck!
The relay is sticking. Replace it.
The most likely culpret is a faulty radiator fan relay or a blown fuse. Fans are intended to force air through the radiator when the car is sitting still and reaches about 200 degrees F. If you turn your A/C on the fans should operate all the time. If the fans operate for A/C you may have a faulty temperature sensor.
your themostat does not control your fans your fans are controled by coolant temp sensor if they are running all the time the problem is in the coolant temp it not working and ecm is overriding it and alowing the fans to run all the time.
