1999 Pontiac Sunfire Heater A/C Control Lights

Electrical problem
1999 Pontiac Sunfire 4 cyl Front Wheel Drive Automatic

Is it possible to replace the lights in the heater A/C control unit of a 1999 Pontiac Sunfire? The unit works fine but doesn't illuminate at night. All other lights work properly. (Dash, stereo & interior) I just can't figure out how to remove the two small bulbs that are meant to light up the unit when the dash lights are turned on. Any help is appreciated. Thanks.
