My clock on my 2008 aveo keeps time but doesn't stay on

Check your cigarette lighter if is there fell there .If something like coin money in there remove it ,then check your fuses there is one broken

In the underhood fuse and relay box.

I've looked through the manual and don't think you can have it to stay on the clock. If you want to have a look you can download it here. https://www.chevrolet.com/content/dam/Chevrolet/northamerica/usa/nscwebsite/en/Home/Ownership/Manuals_and_Videos/02_pdf/2009_chevrolet_impala_owners.pdf

place engine at TDC, remove timing cover, remover belt, install new belt, be sure cam timing marks align and engine stays at TDC, i recomend buying a service manual, they cost about 15 bucks and save alot of headaches for begginers

Hello: You have a wiring problem either in the fuse box under the drivers side dash or the fuse box under the hood, also where the wiring going to the engine control module.

I have looked and looked for this myself. I belive since one of the wires runs to the ecu. for the acc power it is branched off of some other . If you need a good reliable place to pull power. Use the power windows Breaker / fuse its on the passanger side it is on acc power for the key.
The other Direct battery feed for the radio is protected in the left fuse box on the drivers side.

radio and clock dnt work on aveo fuses are gud keeps reseting clock radio is dead

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.

I had to bring my 2004 Aveo to my dealer to have the clock replaced, TWICE!!! Apparently it was a fault with the clock not the fuses. I hope this helps.
