The fan will turn back on after I shut the car off and will not turn off and kills the battery

Relay could be sticking

Is that in the second fuse box attached to the firewall. And it doesn't do it right away it seems to happen when the car is cooled down

Check your owners manual for its location

http://justgivemethedamnmanual.com/nissan/nissan-350z-owners- manuals -- here's an online one if you don't have one

Delete the space between (- manuals). Should be (-manuals) for link to work. Sorry iPad issues

Ok thanks

http://my350z.com/forum/exterior-and-interior/150099-tail-light-fuse.html .....For whatever reason there are 3 relays. Probably at least one of them for when A/C is turned on. The site above was started with taillight fuses, but shows fuse/relay box, and explains how to get to it, which seems not easy. click for full screen Good luck and ...Hi dandy!

The owners manual is lacking on fuse/relay information. dandyoun has the right idea, most manuals have the map but not this one. It says if a fuse blows, replace it. Well duh

Lol thanks guys yea I found a youtube video showing where is was. gonna check them when I get outta work.

Think it might be a relay because when I turn a/c to off it blows harder so it might be a stuck relay. Well I hope. Lol
