2006 Speedo/Fuel Display Goes Out

I am at my wits end here and could really use some help. Started about a month ago, no speedometer or fuel gauge (the display up on the dash). So, somewhere I found out about unplugging the 12v battery and that worked...for a while! After a few times doing that, I read somewhere that it is a sign that the 12v battery is going. So, I took it in to the local auto parts store, they tested it and said it was good. I bought one anyhow since it was about 3-1/2 years old. That worked for about 2 weeks, but now it's back! I've unplugged the battery and again it has ( temporarily ) fixed this issue. The other thing that happens is that it is difficult to turn off and requires you to hold the power button for an extended period of time. I guess part of my problem is I am not sure what to call that display and my searches are coming up with all sorts of things. I have about 160,000 and have had no problems. Any advise is greatly appreciated.

 

Thank you. If I understood that correctly I am past the extended warranty and it will not be covered by dealer. So, the next question is what have people been paying for dealer to replace this? Thanks.

 

I can't believe it, but the dealer took care of it 100% under the extended warranty! They said I was just a few months short of the end of the extended warranty. They had it from a Friday to Monday and gave me a loaner while they fixed it.

Thank you very much. If I hadn't known they probably would have just charged me for it!
