So when I got it the my charging ports didn't work blew every fuse almost instantly and mph gauges/instrument cluster would periodically flash jus thought the bulb was going out.. one day turned on map light and it started pulsating to the music i was listening to along with the instrument lights come to find out the overhead map light cluster the little red accent lights were melting the board so I just took the whole board out (sucks to have no interior lights) thinking it would fix issue the gauges it still flashes an my battery has been losing voltage any ideas on how to find issue appreciate all imput

If you have put in a new battery and didn't code it, it might cause over charging/voltage as the car hasn't been coded properly.

Otherwise I would check your fuses and also if you have a Rosstech cable to plug and find any faults, checking communications for the electric 09 modules.

Thanks Alex for the response it was like this when I got it and of course out of warranty I will be getting a new battery and code it in a couple days to see if that works fingers crossed

Alex is a smart cookie, we know that when the battery starts to lose some charge then you can have all sorts of wierd things happing so its the best place to start for sure.

You'll be surprised at how many places/people install new batteries to older cars and then find that things withing start burning or modules frying.
When your car battery gets older the voltage dips, and the car computer will monitor its age and adjust the alternator/voltage to pick up the difference in the loss of voltage, then a new battery is installed and nothing told to the car computer and so now the difference in the original voltage isn't corrected hence the over voltage created and many issues that goes with this.

In anycase update us on how it goes.
