My gauges and instrument cluster has stopped working?

A lot of the instrument clusters failed and needed to be replaced. With that being said, you need to run a diagnostic check on the one in the vehicle to determine if it is bad. Based on your description, I believe the internal circuitry has shorted causing the high beam light to get power all the time but not nothing else is getting power.

To test the cluster requires a scanner. I don't know if you have one, but if you look through the three pictures I attached, you will find they are the instrument cluster diagnostic flow chart. I am attaching them for you in case you have a scanner or have access to one. Also, the following correlates with the test.

The numbers below refer to the step numbers on the diagnostic table.
2. Lack of communication may be due to a partial malfunction of the class 2 serial data circuit or due to a total malfunction of the class 2 serial data circuit.
The specified procedure will determine the particular condition.
4. The symptom list in Symptoms will determine the correct diagnostic procedure to use.
5. The presence of DTCs which begin with "U" indicate some other module is not communicating. The specified procedure will compile all the available information before tests are performed.

If you are able to perform the test, let me know the results so I can further advise you.

Let me know if you have other questions.

The instrument clusters in these trucks had alot of issues, you may need to replace it. You should be able to do it at home if you have a small amount of mechanical ability

See the attachments below for instructions on how to change the gauge cluster.

Check the wiring and fuses. Pay special attention to instrument panel grounds. I have attached the schematic for the instrument panel. Each page is in 2 parts for clarity.

Hello,

This could be a problem with ground #200 which is located behind the right side of the dash near the "A" pillar. Today's modern vehicles have a lot of electronics and electrical systems on them. People tend to focus on the power side of circuits but forget that it is only 1/2 of the circuit. The ground side of the circuit is the other half. In fact 75% of all vehicle electrical problems are poor or bad grounds. Because of the many electrical circuits in today's vehicles, they will share a common ground, so if the ground goes bad, it will effect many systems. In the diagrams down below I have included a ground distribution wiring diagram for your vehicle as well as ground location and how to inspect a ground for your vehicle. Please go through these guides and get back to us with what you are able to find out.

Thanks,

Hello again,

If you have power and ground to the switch and it goes dead then the switch is bad and needs to be replaced. Please keep us informed.

Thanks,

I've been looking at the wiring diagrams on your truck and I find the main power wire but it may be in the fuse box at the end of the dash on the driver side, opened up the drivers door and remove the end cap from the dash and check your fuses. THis guide can help

this video shows how to change out the cluster if the fuses are good.

Check out the diagrams (Below). Please let us know what happens.

Good morning.

The chances of all the gauge senders being bad a real slim.

I would go with the cluster. Check the connections behind the cluster for any bent or damaged pins.

Try disconnecting the battery and reconnecting it. This should reboot the system. Also I would check all fuses to see if one popped when connecting the battery.

Please let us know what happens so we can keep helping you.

Hello,

It sounds like the BCM is out. To be sure here is a video doing a CAN scan which is the future of car repair you can get one for about $50.00 on Amazon:

Here is how to replace the BCM in the diagrams below in case you need it. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
