  • Hi I have a 07 my flashers started to go slow and now they don’t work at all would it be the relay or the flasher relay controller unit thanks

    • Hi John,

      Did you get a reply as I have the same model with the same problem.



    • Hi I have a t31 diesel headlights are stuck in the down position. Normally when switched on they raise up but stopped working will this be a fuse gone

  • Where is the relays box?

  • The warning bip before starting the engine and when switching off the engine while the front lights still on, of my Nissan X-trial 2.2 litter, YD 22, year 2002 just stop working. What could be the problem?

    • I replaced the Starter Signal fuse, but it’s not receiving power, I checked all other fuses inside and outside in the motor with an electrical test light all work and receiving power, except Starter Signal Fuse, Any advice?

  • Does a x frail have a fuse for alternate 06/07

  • I had a fault on the rear numberplate light(s) of my 2006 Nissan X-Trail (T30 engine 2.2 Deisel) … which I thought was due to a broken fuse.
    Amongst all of the searches I did through Google, yours was one of the sites I visited…. which I found was very helpful and informative … Thank you!

    NONE of those sites, yours included, showed me which fuse controlled the circuit responsible for the rear numberplate lights! (Unless I missed something?).

    So, I decided I had to check EVERY fuse that may have been responsible for this circuit, in both the engine compartment AND the dashboard fuse boxes…
    NONE were found to be damaged/blown, and so the problem seemed to be either a connection or damaged cable issue.

    Fortunately I found the broken wire at the rear hatch hinge point, where the harness passes through the flexible rubber tube into the hatch.
    It is great that I managed to make the repair, but I still do not know which fuse controls this circuit!

    Many thanks again for your great efforts and information.
    Best regards, Malcolm.

    • Hi Malcom , the numberplate light would be fed power from the taillights , so it would use the same fuse. Good job at finding the fault

  • Hi, great site, I wonder if you could point me in the direction to help me fix the lock on the tail gate. It has stopped locking when I lock the other doors with the central locking on the key fob.

    • Hi Mike,
      Not sure if you already resolved this…it happened to me with my ‘06. It ended up being detached wiring where the wire passes near the hinges of the tail gate on the left side.
      Once the wires were reattached, the lock worked with the key fob.

  • I replaced a battery on my Xtrail nissan 2004 and now my radio has stopped working.
    What could be the problem

    • If the radio does not work after removing the battery, then the problem may be due to damage to the amplifier. It is extremely sensitive to the immediate moment of power connection and power surges.
      Contact your service

      • Hi, I have a 2004 T30 2.2 dCi (RHD) which has been the most reliable car I’ve ever had until recently. After charging problem (now fixed) which caused all the dashboard dials to violently vibrate my speedometer is not working everything else is operating normally. I would be most grateful for any advice on how to resolve the issue including what fuses/relays might be involved.
