Hey Tom ==It probably has a loose connection and looses voltage/. GoodluckJoe
Press and hold down clock button while pressing hr/min.
The hot wire bypasses the ignition.
i have a 2005 blazer...there is 2 very little buttons on bottom left of the stereo..just push and hold either one
For me the reason the clock and stereo were resetting was because they were losing all power from the battery. The battery was dead. maybe your cables need to be cleaned or there is a loose connection.
hold in the "clock" button until the time comes up then turn use the volume and channel controls to adjust.
push the set button then within 10 seconds push the seek and scan buttons to change the time.
Does it reset after shutting vehicle off? Could be memory fuse Check fuses
Nothing except resetting your clock and radio presets.
Trouble is brewing, probably within the "clock spring". Take it to a shop that works on air bag systems.
It is designed to stay on. It will not drain your battery.
how do you set the clock on a 2003 chevrolet trailblazer
First clean battery connections, if this does not correct problem the battery needs replacing.
