Cluster radio lights

04 yukon xl denali with Bose

Replaced my factory radio. Used the correct harness to make on star, and steering wheel buttons work.

Now, the lights on my instrument cluster (speedometer) won't work. I have rechecked all connections behind the odometer and behind thr headlight module. All seem to be good.

Any suggestions?

Thanks

Just the speedometer or the other gauges as well

It appears to be just the backlight for he odometer and gauges. All other lights work. I can even turn on the interior lights.
