Hello everyone, I've got a 2001 Chevy Blazer 4WD with a little over 140,000 miles on it. As of recently I've been having a really weird issues. I was driving home from work the other day and all of the sudden a few different dash lights started coming on. The low fuel light, battery light, air bag light, seatbelt light, and the security light. As well as the coolant gauge went all the way to the left to cold and the fuel gauge went down to E despite having more than a half a tank of gas. Now when it happens it eventually turns off and the gauges reset themselves, when it does happen though there is no power loss, no shifting issues, and it starts and stops perfectly fine. Now I know someone might say, "if it isn't broke don't fix it". But in this case it worries me that it might turn into something major if I let it be. As a back story on maintenance maintenance, the battery and alternator are new. And none of the fuses are blown that I can see. My issue is I cannot find anything about it on YouTube that matches my current issue. Someone please help! This is what it does when driving, no power loss just dash lights that stay on for awhile then turn off on its own. No check engine lights what so ever.

 

Mine did that at 116 K. I tried unplugging the connector, then I took it apart looking for cold solders, broken wires, burnt spots, any problems whatsoever. The junkyard had an instrument cluster that read 47 K for $25. I've put 10 K miles on it since then without any problems. It could be programmed to read the actual miles. I do find it scary that I could cut the appeared miles off the truck that cheaply.

 

Do you think that's the road that I should go down? Just buy a new cluster? Because this issue doesn't affect much of anything, but are you 100% sure that your issue is the same as mine?
thanks.

 

Try unplugging the connector, put a little dielectric grease on it. If it does it again take the back off and look at everything with a magnifying glass. Mine appeared fine visually.

 

Ill have to do that at some point, I've heard from a few people telling me that the clusters usually go out on Chevys. So its not really surprising that this is happening to me honestly.

 

Here's hoping you have " I wiggled the plug and now it works" luck.

 

In my case I hope that's the issue. It appears that you can purchase a new cluster for about $500.00, which comes programed to your vin and Mileage.

 

Shaun, try the easiest things first. Please let us know what you find is the problem. Thanks.
