gen 4 HVAC panel is removed by first popping off the main console trims which is held on by 4 plastic clips. Pry the trim with a flat head screwdriver with tape over the tip to prevent damage to your dash. The trim pulls straight out.
Next you'll see 4 screws holding the HVAC to the dashboard. Undo those. Next pull the 3 large ajustment knobs off my pulling straight towards you. Also pull of the small knob that dictates the fresh/recirculated air. There should be 1 screw behind each of the 3 adjustment knobs. Undo these. Undo the A/C and defrost pushbuttons from the plastic HVAC casing. Pull the plastic HVAC casing off and you'll see two(2) #74 blubs with green condoms on them.
The A/C and defrost use seperate bulbs.
LEASAUNCE: THESE BULBS ARE NOT SMD LEDS. Each pushbutton uses a small bulb in the button that is not easily replacable as it is small and attached to a plastic base.
Before you try anything, pound you first around the area a few times. THe bulb contacts in this are a shitty and come loose very easily.
Bulb on the left is the A/C bulb. Bulb on the right is a #74. You can see its way smaller:
