Clock might be mad? It should change to be honest if you press the MIN or HOUR.

 

ecm glitch?
iirc, the clock doesn't have am or pm, so you could pull the batt terminal at 1 o'clock in the afternoon too if that's the case, ;-)

Mine kinda does that.

I have to press the hour and minute hand pretty hard.
Sometimes nothing happens and I have to jab at the buttons.
I got a feeling that the contacts might be getting some crud on them from the air blowing in from the outside, and since there is no cabin air filter I wouldn't be at all surprised if that's the problem.

See if you can get a dowel or something that can get a direct push on the knob and see if that does any good. If not, you might have to remove the dash to get access to the clock. Not a big deal, a couple of screws. But I've never removed the clock so I don't know what's involved to do that.

Once you get it out and taken apart some electrical contact spray might do the trick.

Let us know what you end up doing.

Good luck.

Could be worse, mine does not even work at all most of the time. lol. Sometimes it's on bright, look down again and it will be black. lol.

 

Some surface-mount resistors probably detached as the solder weakened and cracked from button pressure. I'd take the clock out and resolder them. And after that press the buttons gently. I guess the engineers didn't properly build in the support at the back of the buttons, so the circuit board flexes as you press on the buttons, breaking the solder connection.

Sometimes mine will dim so I can barely see the time. When I tap it a few times, it becomes brighter. I guess after all the years it has been working, time is running out. :laugh:

 

My clock set buttons haven't work for over 10 years. I just assumed the contacts corroded. At the time change I just take off the negative battery terminal and reconnect at 1:00.
