hey guys..had a little snowfall here in VA..anyway, as i was driving i happened to look at my left side mirror and to my amazement the ice that was stuck on the mirror did not melt at all. the passenger side was ok..it was able to melt the ice..unfortunately, on my side it wasnt able to. any ideas before i take my car to the stealership?

i think its a safety hazard..lol..thanks in advance..oh ya, on the owners manual it says that it goes on automatically and it varies with the temperature..i miss my 04 4runner that had dual heated side mirrors linked to the rear defroster..lol..thanks guys
