My dashboard lights are out...anyone knows which relay or fuse need to check?

I hope you have the problem fixed by now, but, it is the ABS control under the truck. You need to go under the hood and open the fuse box and disconnect the 60 amp fuse for the ABS, this will turn it off before it burns up. This however will also cause the traction assist off light to stay lit all the time. To the fix the problem you can pay tons of money ($700 or so) to have the dealership install a ABS control and the problem will happen again over time. Or, remove it yourself, go on ebay and ship it off to a guy who repairs them for about $150 and you will never have the problem again. Also, if you wrap your cable ends with plastic and protect them good, you can still drive you truck while the part is being worked on. It takes about a week.

Depending on what type of trailer you have, a blown lightbulb on one marker could kill them all (like the old Christmas light strings). Look at those, and make sure your ground is good.

there is a fuse/relay panel underhood, also another underdash. check fuses with a testlight if possible. make sure the reostat( little wheel beside the light switch) is in the proper position. The dashlights are a seperate issue from the turn signals, unless it's an underdash wiring issue. check the fuses and reostat and let me know what you find.
Good luck

I found a solution to my problem on the Internet and it worked a treat

My problem was that the dashboard and both rear lights would not turn on, but the fuses were okay and nothing had been changed

It turns out that in the passenger footwell there are a few relays right in the footwell where a person would put their feet. At first it was suggested that you push your feet really hard against the front of the footwell to see if that helps, and it did, but the lights went out again later. So it was then suggested that you look for a loose relay box where the feet go (on the left hand side at the top of the footwell, nearish to the bonnet release catch). It turns out there are 2or3 relay boxes there. SImply push each one to ensure that it is correctly seated, and voila the lights work perfectly again.

A simple fix that costs nothing, saves a potentially costly visit to a garage, and can be undertaked without any tools are even needing to open the bonnet.

May not solve the problems of those blowing fuses etc, but certainly worked a treat for me

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!
