1. Locate the clock fuse. The fuse box is located under the hood of the car, on the driver's side. The clock fuse is labeled "CLK" or "Clock".
2. Check the fuse. If the fuse is blown, replace it with a new fuse of the same amperage.
3. If the fuse is not blown, check the clock itself. The clock is located on the center console of the car. Remove the clock from the console by gently prying it out with a flat-head screwdriver.
4. Inspect the clock for damage. If the clock is damaged, it will need to be replaced.
5. If the clock is not damaged, reinstall it in the console. Press the clock firmly into place until it snaps into position.
6. Test the clock. Turn on the ignition and check the clock. If the clock is still not working, there may be a problem with the wiring. You may need to take your car to a mechanic for further diagnosis.
