Dimmer not lighting up Gauge Clusters
 

My ZR-1 rolled in last night and the first thing I notice is the dimmer adjuster did not light up the gauge clusters at all.


If I moved the dimmer all the way up the house over lights come on and works, but nothing on the gauge clusters.


Any idea what it could be?

I checked the "cluster" fuse and it was working.


Looking at manual it said if the bulb for the cluster gauges was out to contact a dealer.


Let me know if any of you have experience with this. The only thing that lights up at night is my orange speed odometer and orange screen on my radio.

As shown is this attachment, nothing else is lighting up besides the orange lights and the house lights. Is there another fuse for this besides "clusters"?

Ok so,you are in a dim low light garage , correct? When you turn the light switch on the left hand dash to parking light or headlights on, the entire cluster has no backlights? What about the a/c controller and radio? Do they light up? When was the last time they worked for sure with park or headlamps on? Do the exterior lights (parking etc) work? Do the headlamps pop up?

Check your CCM codes after the above and see if you have a code 74 dimmer switch. Any aftermarket alarms, radio, amp etc?

Following up on this incase any new zr1 owners have this issue and search for it.

As mentioned, I had checked the "instrument cluster" fuse, which was not blown but the gauges were still not working.

This caused me to check every fuse before I sent it in and I found that the "tail light" fuse was blown.

Once replaced, my front gauge lights started to work.

All fixed.
