[newbe]Dashlight/speedometer/fuse

the main unit of the dash(with the flasher and the speedomerter) dosent light up(i mean the backlight) and the speedometer dosent work neither,

all the other gauge and light work, when i start i see the belt light(and all those light) but not bright(if there is a little bit of sun i dont see them)



so i did a little bit of search on google and the first problem for the speedometer was a fuse to change(captain obvious here)

so i find the fuse shema here (page 13 for my jeep)

but i would need some help to sort witch fuse do what,



i manage to find the 2 fuse box(yeh),



i hear about some kind of motherboard corosion too affecting principaly the speedometer area(i hope that's aint the problem)



i hope i was specific enought,



and thanks in advance,





Ps:if anyone had a sync problem with there tram, how mutch did it cost you to fix it.



Pps: english is not my first language, if there is anything you dont understand please tell me.
