'97 Camry? You're looking for the 3rd/4th Gen section, but I'll answer your question anyways
Just get a phillips screw driver, and take out the screws that hold the cluster bezel in place. I think theres a couple of screws on top and clips on the bottom you'll have to snap out. After that you should have access to the 4 screws that hold the cluster in place. Remove those screws, pull the cluster out some, disconnect the connectors in the back, and pull the cluster out. Now replace that bulb.
Feel free to correct my instructions. It's been over a year since I did some work on my ex's 4th gen's gauge cluster. kthnxbye
