Changing the clock - 2003 Chevrolet Malibu

Could you post a photo of the clock and the area of the dash it is in? There is usually two different methods of changing the time on the clock.
The older method is to use buttons or a roller switch that are on or near the clock display. The newer clocks are usually setup on the touchscreen by going to the 'settings' area.

What question

Make sure the clock is set to the correct time zone before trying to set the time.

there is a button located on the end of the turn signal that controls the clock function on the dash and the radio clock.

Dear Sir!
Beside the digital clock must be 2 switches, one is for hours and the other is for minute, if it is not when the time is 12:00 take out the clock fuse and enter it again the time will be automatic 12:00.
The clock fuse is under stearing wheel.
Hope to hepled you.

Try this, put the key in the ignition and let it be on the first turn right marked "ACC" or you can turn off the stereo and you will notice that only the Digital Clock screen will show. Turn the Volume/Audio/Sel knob and press on the "DISP" button simultaneously for about 4 seconds then release the "DISP" button. The digital clock will start blinking, and then use the Tune/Seek arrows pointing up and down to change the time. If the hour digit is blinking change the hour and after you have changed it press "DISP" then the minute digit will start to blink change it using the arrows, when you are done press "DISP" again or leave the clock for between 4 to 8 seconds the clock will start working normally.

I hope this works for you.

Good luck!

To reset the clock, with the ignition on, push the clock button and then turn the "i" dial to change the hours. Push the clock button again, to change the minutes, etc.

Hold in the clock button. While holding, press seek forward or backward to change the time.

There are two depressions just under the clock, pressing one with a ballpoint pen changes the hours, the other changes the minutes
