To get the AC and heater knobs to light up on a 1996 Volvo 850, you typically need to check the bulb behind the knobs, as they often burn out over time. Remove the trim around the climate control panel to access the bulbs, then replace any burned-out bulbs with new ones. Additionally, ensure that the vehicle's interior lights are functioning properly; if they aren't, it could be a fuse issue. If the knobs still don't light up after replacing the bulbs, consider checking the wiring or connections for any issues.

Microscopes typically have knobs for adjusting the focus (coarse and fine adjustment knobs), magnification levels (objective lens turret), and the stage (stage control knobs for moving the specimen). Other common knobs include the condenser adjustment knob for controlling the amount of light passing through the specimen and the mechanical stage knobs for precise movement of the specimen.
