| During a trip along wa highway 2, westbound thru stevens pass, the temperature was dropping as indicated by the vehicles outside temperature indication. as it traversed from approx 42 degrees f to 36 degrees f all windows fogged severely so as to render no visibility. the defroster was engaged during this event. this vehicle has a manual hvac system. this has occurred numerous times as the temperature traverses below 36 degrees f, all times result in excessive cabin moisture and window fogging. this event has been reported by other 2010/2011 gmc/silverado/avalance, etc owners. gmc is aware but has no fix and dealers offer no fix. | |||
