The dash lights do not work! I can't tell how much gas or how fast I am going anymore!

The reason the light on the dash flashes quickly is to tell you a bulb has blown just locate which one and replace said item, or go to Halfrauds.

Check the fuses and connections that power up your dash board. Your car manual will tell you the location of the fuses and what is for what.

Has the light been going to out slowly or happened all at once?

Have you turned the Dimmer all the way off or did you blow a fuse?

There is a Wheel or know that you can adjust the Dimmer on the Gauges, check and see if someone accicently turned it all the way off..

Get an Auto Electrician to trace and fix the problem. There are partial contacts in the wiring system.

not something you can fix on the side of the road
most mobile phones have a torch function
two dollar led torch from a gas station or convenience store

if not the instrument fuse . a relay
yes could be a faulty on /off light switch

Either the dash light dimmer is turned off or the dimmer control is defective.

Replace the instrument cluster.

There is Supposed to be a Small Dimmer Dial or Switch next to the Headlight On Switch.

First you need to verify that your truck goes into 4X4 HI or LOW; try putting it in 4X4 Low you will be able to tell by feeling the truck engage and not being able to go very fast.
If it doesn't then it could be the lock out selenoid; I had this problem when I bought my truck from my friend. Luck for me it was still under the extended warranty. If the truck goes into 4X4 then it could be a bad bulb. Good Luck

check the fuses first, if they are ok then check the wires going to the instrument cluster
