Here are some additional tips for finding the fan relay in a 2001 Jetta:
* If you are having trouble locating the fuse box, consult the owner's manual for your vehicle.
* The fan relay may be located behind the battery, so you may need to remove the battery to access it.
* If you are still unable to find the fan relay, you can contact a certified mechanic for assistance.
