Gauge Cluster Issues

On my drive to work today my gauge cluster went out. None of the gauges, check engine lights, or turn signals work. However, the caution lights, door ajar light, and odometer do work.

None of the fuses are blown as far as I can tell. I looked under the dash for anything loose or broken. Nothing seemed out of place. I then took the gauge cluster out and reinstalled it. Still broken.

Any suggestions? (sorry for any formatting issues, I'm on mobile at work)

Edit: Forgot to mention I have an after market head unit and had the heater core replaced last winter.

Edit 2: All of the back lighting works.

Check your fuses under the hood.
Recheck your fuses under the dash again especially fuse #15.
Check your wiring for your head unit. Some guys have had cluster problems when their head unit is wired into the cluster harness.
Is your head unit working properly ??

You could try to enter the cluster check mode to see if that tells you anything.





There's more information in the service manual...

I've heard of a single gauge in the cluster going bad but not most of them all at once.
I think you've got a power supply problem.
