well i dont know if its just me but i'm going to post this to find out. does everyone have to drive on with there defrost on all the time to keep the window visibility in check. i understand that in the winter your going to have this due to the temp change but this has been going on for a long time. soon as i turn off the defrost for the front and rear i cannot see, i dont smell anything sweet like coolant so i dont think that its the heater core. i just rather drive around with it off to keep some of that extra load off the engine. thanks guys

 

I dont know. I dont have this problem.
