Moisture in Dash Display

I have moisture in the dash of my 2005 Rubicon. Does anyone else have this problem. I have had it apart several times to wipe the moisture away. If it sits in the garage or in the shade, there isn't any moisture, but let it sit in the sun, the dash display fogs up, sometimes more than others. I have even glued in some of those packets of moisture absorbing pellets that often comes with new electronics to keep them dry during shipping but no luck. It has been this way since new really. Any ideas here??

Thanks!
