Climate control cluster doesn't light
 

The light for the 3 control knobs for the climate control (beneath the radio)no longer lights when the running/headlights are turned on. All opther lights work fine. It appears to be a blown bulb(s). How do I get to the bulb(s) to replace it? The truck is a 2003 SCREW FX4.

there are bulbs behind the HVAC controls.

I think the process was remove the oval surround around the radio ( including the HVAC vents ) , then the screws around the HVAC controls are visible.

There are a few spring clips that hold it on. You can use a trim puller, or reach in the HVAC vents, and give a good pull out.
