Hi.

I just finished an amp and speaker installation today on my 2007 350z roadster. Everything worked perfectly first time which immediately had me worried as this never happens.

I have now found that when I press the button to open the boot by the number plate, nothing happens. Also, when I press the fuel cap button by the steering wheel nothing happens. No noise or anything.

I can release them manually using the cords in the glove box and bot and I have checked the fuse in the drivers footwell and this is intact.

Does anyone have any idea what I have done and how to fix it?
