I bought this the other day. None of the gauges are working. At all. I did check the fuses as labeled in the book, but all know sometimes that information is incomplete. There may be something on a fuse that's not listed. If someone could please supply the known fuse information as well as associated wiring diagrams that would be great. Also, if you happen to know if common causes of this, I'll take that too if course. I want to get this car ready for tax season sale ASAP as dad has a used car lot and I stand to make a nice easy $1,500.00 if ready in a month or so.

There are 3 fuses that run the system fuse# f2, f13 and f26 in the interior fuse panel here is a guide to help you test the fuse and to test for power at the fuse I also have included the cluster wiring diagrams so you can see how the system works,

Check the fuses with the key on and I would check the grounds as well, if they are okay the cluster is bad and needs to be replaced. Removal and Installation

1. Note: If installing a new instrument cluster, it is necessary to upload the instrument cluster configuration information to the scan tool.

Remove the instrument cluster finish panel.

2. Depower the supplemental restraint system (SRS).

3. Note: Release the upper steering column shroud by pressing the sides inward.

Remove the upper steering column shroud.

4. Remove the screw and the transmission range indicator from the steering column.
- Disconnect the transmission range indicator cable from the shift selector arm.

5. Remove the 4 screws and the instrument cluster.
- Disconnect the electrical connector.

6. To install, reverse the removal procedure.
- If a new instrument cluster was installed, download the instrument cluster configuration information from the scan tool into the new instrument cluster.
