Re: My Heater Core is Blown !!!

I haven't seen it here, but if you serarch for "Blend Door" issues with dual zone there will be a write up on it. It's one of the things that's recommended to be changed while you're tackling this. Since the dash will be removed.

There is a lot involved, but it is do-able if you have the willingness to try, and learn. Sorry I'm not more help.

Re: My Heater Core is Blown !!!

i thought my heater core was going i was smelling a lil antifreeze in the cabin and my windows would fog up a lil bit. i put some stop leak in the radiator and bam! no more smell no more low coolant and thanks gooodness no more foggy windows. but if yours has a big hole i dont think it will work. do you have a puddle in side the passenger floor? usually you get a nice mess when the core goes out bad. you may be able to try some leak fix its cheaper and way easier than taken out your dash. just a thought.
