gauge cluster issue, help...

Now, another problem comes up!
a couple of days ago i've notice that some of the lights on my gauge cluster lights comes on then turns off. The lights that come up are the brake light, battery, and the 3rd looks like an intercooler (the very bottom left corner in yellow) not sure what it is. I just changed my battery yesterday and that didn't fix the problem. The lights would just randomly come on then turn off until yesterday, now they stay on all day! what would you guys think the problem might be and what things i should look at? Would it possibly be a ground wire or something? i don't know...any input would help!
Thanks

Sounds like a bad connection somewhere. Try taking out the cluster and then reinstalling it. Could be a bad connection somewhere else too. Not sure besides that though

my brake light kept coming on and staying on...check your brake fluid...if its not full the brake light comes on...if you have plenty of brake fluid then you know its something electrical....if it needs to be filled...then it might actually be 3 different problems

The one that looks like an intercooler is radiator. Sometimes on my gs-t if the rpms go to low (500) those three flicker. But they always go off.

try to reset the computer by removing the negative battery cable for a few minutes. it worked when my seat belt light stayed on.
