Battery Light Flickers In Message Center When Driving

Hi everyone, here's a stumper. I have a 2001 Chevy Silverado with a slight electrical problem. The battery light in the message center flickers on from time to time and sometimes stays on for about 30 seconds and goes out when ever the engine is running. I do think it's weather related. As soon as the temp seems to drop below 50 outside the problem seems to minimize and even go away for quite awhile. THE VOLTAGE is good. 14volts plus all the time. The volt gauge don't even flicker when the battery light comes on. I've checked with a volt meter and all the grounds for the engine are good. I know some friends that have 2003 and new chevys that have a dash cluster problem. They say the solder on the connector pins can be bad. Can anyone help. Low mileage truck that I bought new. I don't want to take to the dealer locally. They'll spend at least $300 or more of my money. The alternator charges fine and isn't grounding out that I know of. Thanks... Lots of luck with this one..

I have the same problem with the battery light flickering. I have a 2002 Sliverado. The problem started about 4 years ago. It will not happen for weeks then it will start again. The dealer could not find a problem but charged me $90. Recently the battery died, it had a cracked case. That seemed like an unusual way to fail so I suspected overcharging. I have a voltmeter connected to the battery and alternator which I can monitor while driving but have found nothing unusual. A couple of years ago I had the instrument panel out and measured signals there but did not know enough about how the message center is controlled to find the problem. I'm currently trying to figure out how the message center gets it's signals so I can monitor them to see if there is a correlation between the light coming on and any of the signals. This is not easy.

 

Any tips would be appreciated.

Hello,

 

Same problem here. I have been seeing this for a few years. It happens for a week or two then works fine for 6 months or more. When the battery light flinkers it shows no pattern. Replaced battery, chased the positive and grounds, checked connections and checked for codes........nothing to date has helped.

 

Looking forward to any feedback or thoughts.......

Thanks,

Wondering if anyone has come across a fix for this. From the list of people that responded initially, it looks like it's limited to 01 or 02 trucks.

My light still flickers intermittently with no ill effects. Just kind of annoying.

Might be a stupid suggestion, but have you checked the negative connection on the battery? I had an H3 and the lights started flickering on the expressway as I hit bumps...ended up being a loose negative connection on the battery.

      OCI, not when but why?

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact.

      Transmission jumping out of gear while driving.

      By JimCost2014 · Posted

      Probably a one and done post, but do you have a CEL on the dash? Was having issues with my transmission, fortunately only a week, and it turned out to be the transmission harness. Valve body was in good shape, so new harness with all the sensors attached, new fluid, and filter. Seems to have worked so far?

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.

      Weird click noise when revving my truck?

      By JimmyB4 · Posted

      Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!!

      We’ll have to agree to disagree. I didn’t experience or know anyone who had a decent car after 100K miles in the 60s through the 80s that were daily commuter vehicles. Unless they were collector vehicles. Of course things cost more due to inflation. But we also make more money. The biggest money drains these days are things people think they need today versus what we require back in the day. Like cell phones and internet as examples. Another example is where you live. Cost of living varies from state to state. I would need twice the money to live in NJ vs Texas in retirement. The car you recently purchased was less than my first car with inflation at 3000$ in 1973. I didn’t have air, electric windows, cruise etc. Purchasing power is equivalent, you just have to do the research.
