Poor Design of Heat Distribution on Windshield
 

I recently purchaseda 2008 GMC Sierra SLT 4 Duramax, the heat distribution for the windshield seems poorly designed for anyone owning this that lives in an area where there is alot of snow...Has anyone had any problems with snow and ice building upcausing a problem seeing out the windshield. The snow and ice builds up so quickly in front of the driver and passenger side because they dont get any direct heat to help in melting the snow and ice away. Any ideas for spreading the heat out across the windshield better??
