A few questions and a few basic steps to help locate your problem.
Have you recently replaced your stereo or had electrical work done on your vehicle where the gauge cluster was removed for any reason? Check that all connections are firmly pushed in and are not lose. Also confirm that no wiring was "clipped" between the panels. You may be shorting a cord. If you recently had some electrical work done by a 3rd party (or a Toyota repair center) confirm that they did not accidentally "clip" an electrical line while putting your interior back together.
Can you reproduce this problem every time when the weather is hot? How about when it is cold? You may have a fuse that is old or partially broken, where the electrical connection is "fair" after its been sitting for a while, but then goes "bad" after a bit of current has gone through it. I know this sounds impossible, but at this point, its just a step in troubleshooting.
1) have a quick skim through this page:https://www.celicahobby.com/forums/...e-room-and-center-junction-diagrams.html
2) Pull and replace the [interior] Center Junction Block Fuses # 12 and 19, 20, 21, 22 with known good fuses. Fuse # 22 is the most likely cause, if your issue is fuse-related.
