I had a failing core in my v70 series recently. My suggestion to you is not to procrastinate, do not try to use a sealer, do not even try to use the heater until you can replace the core. Mine fogged up the windows and I just could not get them clear, aside from being dangerous, I had migraine headaches. Since I replaced it, I have had none. I procrastinated for almost two years, and two almost accidents.

Don't try to avoid the inevitable 9, bite the bullet and fix the car. That is just my opinion.


Try to have a merry Christmas Though!!!
