Sidelights not working

My sidelights and number plate lights have stopped working, main lights and fogs work fine.
It started when I tried to change the front side lights to led ones I bought from ebay after one of mine had blown, the led's didn't work, one lit up then went out, since then the tail lights and number plate lights don't work.

I found a blown 10A fuse in the passenger footwell fuse box but replacing it hasn't fixed the problem.
At the moment the side lights (front) are missing as I'm waiting for replacements so not sure if this is the issue but surely the rear lights should work?

Any one able to offer any advice?

Many Thanks Brian,
According to the above fuse no.27 in the drivers footwell should be the one.

I'll check it tomorrow and report back.

Cheers
 
Let us know also there is fuses under bonnet as freddofrog has listed

yep under-hood = under bonnet ;)

just too many fuses IMO

#5 = CW3 Driver's Under-dash Fuse/Relay Box
#6 = CW3 Passenger's Under-dash Fuse/Relay Box
#7 = CW3 Under-hood Fuse/Relay Box
 
Success!!

With a bit of contortion-ism I changed the 10amp fuse (no27) in the drivers footwell and the lights are back on except for the one that's blown.
Picked up some fuses yesterday and bought the wrong ones, the guy at my local auto spare store sold me the mini blade fuses telling me those were the ones for Japanese cars but I found out later I should have bought micro, my fault for not taking one along for comparison. Anyway the mini fuses still fit but protrude a little as they're taller.

As said above, there are a lot of fuses on this car so I've ordered a truck load from ebay so I don't get caught short again.

Thanks to Freddofrog for the detailed info.
 
it's a good job forums don't use skype :lol: ...
