hey all! well after going all last winter without a heater, i decided i would fix the heater in my 77z this year. i could survive without the heat, but not seeing out my windshield isnt good.( last year i ran over a cement median!!!!) i went out to fix it a couple of weeks ago but after lying there on my floor looking for a few minutes i decided i might survive another winter. but now i decided to fix it again so..... first off, i want to make sure that my heater core is the problem. my symptoms are, whenever i turn on the heater all the windows fog up with a film, and when i turn the lever to "cold" i can hear water squirting out from somewhere. now what do i have to do to fix this? it looks like it might be easier just to yank the whole dash out! anyhow thanks for your input.
