Wheather Radar Don't Work
I've found the solution
Check your FSUIPC installation.
Re-instal your version of FSUIPC, then go to your FSX installation folder => Module => delete FSUIPC.ini.
A new one will create when you'll start FSX.
For an active WX Radar, just push AUTO and L/R buttons on Pedestal and WX button above ND.
Enjoy your flight Captains
