Cooling fan failure
Have 09 Jetta 2.5. Parked the car last night, didn't
leave anything running that could drain the battery.
This morning tried to start the car; nothing. Battery
was stone dead. Didn't crank. Tow truck came with
the battery boost jump machine thing and it started
instantly with the turn of a key as well as the cooling
fans. Drove to work, removed the key and the
cooling fans continued to stay on. Got out of work
after a 5 hour shift and the battery was dead. Had a
co worker try to jump my car with cables. As soon
as the cables made contact with the terminals the
fans came to life with no key inserted. Jump didn't
work so called the tow truck again and repeated the
process and the car came to life. Had alternator
tested and its functioning correctly but the battery
is dead now. Any input on what is happening with
Are you talking about the radiator fan
Because if when trying to jump your car the fans automatically turn on, something but I don't know what at this moment is keeping your fan running constantly so it's running your battery down
Stuck radiator fan relay,if fans continue to run.
Yes I'm referring to the radiator fans. T_S_T, is a stuck relay I can myself make in stuck with limited knowledge and tools?
Beat thing to do shaun ,is remove the relay if fan is running when you cut the car off,this will answer the question,and yes it is as easy as removing a fuse.
T_S_T, thank you for your knowledgable input; it is greatly appreciated. Could I possibly trouble you for a diagram or a description of where the relay is located and instructions to do so?
And do you mean remove the relay each time after the car is cut off? Or remove it and keep it removed until I can get a new relay?
Okay, had the mechanic take a look at it. In my case, it is the fan control module, which is located on the back of the fan. Hope anyone who has this problem is helped by this!
