There are extra fuses provided for you in the cover of the fuse box, they will be labeled as such. Just make sure you use the same amp fuse for whichever fuse is blown.

While wiring up my EVO-R LED Rear Fog Light, I happened to ground a wire that popped this fuse. When I hit the brake, the lights lit up, but not with my daytime lights. I prolly spent 2 hours checking the footwell fuse box and the 1 under the hood. Could not find the right fuse. Then decided to investigate further in the underhood fuse area. There are actually 2 fuse boxes in there. 1 is clipped onto the passenger side bulkhead vertically. Once you get it loose and remove the cover, the fuse you need will be in there. If memory serves me right it is a 10 amp fuse. (Red in Color I think, not Maroon which is 7.5 amps if I remember correctly) Swap that out and you'll be fine.

You can get fuses at any car store, this is what you want:

If you see the little strip inside is clean and unbroken, the fuse isn't popped. If it looks charred inside and the connection is broken, the fuse is blown and needs replacement.

Here is a link to order a set: LP MINI Fuses - Low-Profile MINI® 58V Blade Fuse - Littelfuse :tiphat:

I always keep a pack of replacement ones in the glove box just in case something pops.

Just go to any auto parts store and ask for a "taillight fuse for a 20xx 370Z". If they can't look up the amps and physical size, find another store.

For more info in auto fuses in general, check out https://en.wikipedia.org/wiki/Fuse_%28automotive%29

Now I am very interested to see if it is the fuse.

so i checked all the fuses in the one right by the battery...all of them seemed cleaned and unbroken, but none of them even remotely sounded like they were part of the tail light connection

however there is a big fuse in the fuse box right under the brake fluid labeled "DTRL Relay "...could that be messed up? How do I check that one? I can't seem to get it out.

Doesn't seem like it's a fuse problem though :(
Or I'm just not doing it right

Did you check the second fuse box? There are two.

So there's the relay fuse box right under the brake fluid that I can't seem to get the fuses out (after opening the cover)

Then there's the long vertical fuse box right by the battery, checked all the 10 amp fuses, all were clean and in tact

then there's that other one you have to remove the shroud for by taking out the screw in caps right by the battery and vertical fuse box...I couldn't even get the darn thing open, spent about 20 min, but there were only two relay fuses, one was IPWD or something like that and the other was VVWL or something... both were relays, and since I didn't know how to get to the other relay by the brake fluid I didn't even bother.

Then the fuse box right under the dash/steering wheel on the drivers side didn't seem like there were any tail light fuses so I didn't bother looking at any of them.

Is there something I'm missing here?

That's the fuse box I was referring to, if it is not one in there, then it Should be one in the footwell fuse box. Why Nissan in their great wisdom decided to have so many.. :confused:

the only one that remotely has any connection to the tail light int he footwell fuse box is called Stop Lamp - is that the one??

https://lh6.googleusercontent.com/_7...s512/photo.JPG

but I already checked that and that is also clean and in tact...

Looks like I'm gonna have to take it into nissan to find out what's going on
:(

Check fuses #52 and 53 in the IPDM-E/R (next to battery)

Edit: And fuse #59, if you have DTRL

sorry for the noob question, but how do I know what fuse correlates with what number? (ie what fuse is #52?)

and don't all our cars have DTRLs? I saw the relay fuse in the box right next to the brake fluid but couldn't get the fuse out to check it...it's quite large and the fuse puller doesn't work on that lol

SouthArk370Z 11-29-2012 01:28 PM

Look on the IPDM cover and it will tell you which fuse is what.

More than likely when you had some part replaced or panel, the body shop probably disconnected some wire or ground and either failed to connect it up properly or a wire may not be grounded properly or even pinched or cut.

If all your fuses are good then you need to remove all the connectors to the tail lights and make sure they are all seat fully and locked in, the whole issue is BS because something the body shop did screwed up the wiring.

Note you need to check your fuses with $15 multimeter from sears for continuity, not just by sight as the fuse may have only a hair line break and still look good.
