2008 Volkswagen Jetta - 2.5L 5 Cylinder
Radiator fan continues to run after car is off. Runs for about 30 minutes or till battery is dead.


I have a 2007 VW Jetta 2.5 L - radiator fan stays on constantly, even after shutting the car off. Have to disconnect the battery, because there is not a fuse / relay anywhere under the hood or within the inside car panel. Anyone know what could cause this? - as I understand it from research, my car does not have a Fan Control Module, either. Any and all information greatly appreciated.

the fans continue to run after the motor is turned off and drains the battery dry. help

Electrical fan run for a long time after turning the engine off. It make big noise while turning. it turns off at certain for some seconds and starts to run again and again. for a proximately 5 minutes. I took it for service in March 2014 and reported the issues and was told that they cannot find any fault with it, and I should just drive it. This grains my battery.

Please help.

Fan assembly replaced. Dealer said there was a short in the electronics which led to fan not turning off after car was shut off.

I am having a similar problem with my fan...
I noticed in the summer of 2013 only 1 of the 2 fans were running.. So I decided to order a new fan! Had it installed by PepBoys... This was early 2014.... Since then, my fan kicks on after my car is turned off! If I get out of my car, & lock it, & the fan doesn't turn on, as soon as I unlock the car, & open a door, the fan kicks on. It seems to be getting worse, & the Volkswagen dealership can not find the problem. They replaced the entire fuse box under the hood (because my wheel well cover was ripped off of my car, & salt got in a did some damage). Thinking that was the problem, but it didn't work!! I need help, & am out of options. (They said possibly the ECM, (Engine Control Module) but was not sure that would even solve the issue!

After having my battery replaced, I noticed my engine light was on and my fan was running "hard". It also runs for 10 seconds after my car is turned off. Diagnostics stated "cooling system malfunction".

Same thing as described in other posts. After listening to it run for about 3 minutes, I turned the car on again and turned it off. The fan turned off afterwards. I have a feeling this will happen again until the fan unit is replaced.
