windshield ice up while driving

Unbelievable. I can't get to work because every 30 seconds on the road a layer of ice forms on the windshield and visibility is reduced to nothing.

I pull over, scrape it off and go again. Another layer forms, and I pull over, scrape it off and go again. This happened 3 or so times before I decided to just turn around and go home.

Everyone else on the road appears to be fine. What the $#!@ is wrong with my car? I have the defrost on but it only makes it worse.

Im betting this is because of my busted heater core... From what I gather some of you here don't have a working one either...

So whats the secret? How do you keep ice from forming while driving...? Recommend any products? At least until I have a chance to replace the core...

Yeah, this is really going to be a problem. It will be a few days until the heater core gets here... Just looking for a temporary solution.

Im going to try Rain-X de-ice windshield washer fluid. Is that safe to use in our cars?

Washing windshield helps with deicing but with no defrost heater... I would not dare to use it. I don't know if you can find any 12V heater to use inside the car... But you really need the heater core.

It forms on the outside, and only while moving above 35 mph.
Ice starts to form even with blades constantly on set on the 3rd setting.

Eventually I have to pull over and if its not bad the blades clear it up after about 20 seconds.

I found some heated wiper blades online, may be a nice upgrade to do for the future too.

I was hoping maybe there was some kind of wax product I could apply to the windshield that would resist ice. Have been searching but can't find anything. Im going to try rain-x, I read good things about it.

Of course this is from the heater core. You are spraying water vapor onto a cold piece of glass. What do you expect?
Turn off the defroster and roll down a window..OR fix the heater core.

Are you icing up on the inside or outside?

You can buy deicer windshield washer fluid to help you in this situation.

Well then my original reply is worthless. Your mention of the heater core had me thinking the frost on inside.
Is the heater core blocked or leaking? Is air coming from the defrost vents? Obviusly not hot air anyway. You might have heater valves stuck or servo motors for the air flaps inoperative.
I'm assuming the engine is getting up to temp.
A smudge pot on the dash for now I suppose.

Temporary Solution: Keep a Hair dryer in the car with you and cigarette lighter adapter for the Power outlet

Ya know, thats not a bad idea. Cheap power inverter for the cig. lighter (which comes in very handy for lots of other things), tape the drier to the dash and off you go.
