Strange clock problem?

[SilentMatt]

I know this is an old post, but I have the same issue as Timosoren. 2009 with no diode in D1, so I went ahead and added one...
I didn't find any cold joints or any other issues with the board, but when I plug it in without the housing, I can make LED's D3 and D4 flicker. I put it all back together and still have a dim D3 LED but after a couple days the clock still has the correct time.

Not sure if it was the taking it apart or adding the diode that fixed it.

It could've been a combination of either, to be honest. Those modules are simply a flawed design, they literally "bake" in the sun over time and it plays hell with their circuits.

Mine *knocks on wood* has been fine since I changed it over two years ago, but I've used a sun shade ever since I got the car. This new module hasn't been exposed to nearly as much direct sun as the old one most likely was. What I still find odd is that the factory module died after 6 months. lol

Most usually end up with a broken solder joint because of the constant micro expanding and contracting from temperature change, the diode most likely fixed it for you in your case.

Well, nice while it lasted.... It was on a random time when I drove it today.

I am new here as just got car for a work car and put new clutch and battery in it. Once done i noticed the clock going to 1:00 after every key cycle. Also my radio is completly dead. Nothing. I don't care much about the clock, but want to get radio working again. Any one have ideas? Not any fuses as check them all. Thanks

Did you make sure you have power at the fuses? The AUX button on my radio doesn't do anything, I think the electronics in these cars are just sub par. Hope GM made the ECU...

Do you know if you had a radio before? if so it sounds like the memory circuit. There is a fuse for that, check power to it.

Had the same problem with the clock. Fixed it by tightening the battery clamps as they were loose.
Heat and cold played a big role as metals expand and contract, resulting in my car loosing power.
