sounds to me like your heat core is going bad. Thats what mine did and I couldnt figure it out and then a couple days later it started leaking. I havent had it do it since I replaced my heat core.

 

100% a heater core....does it smell sweet?

 

it has a smell to it but not all the time. more like anti-freeze type smell i guess and also the glue stuff that holds the windsheld the gule when it gets warm it like runs down the winsheld but that cant be the main problem cuz my side windows on the front doors have the film mist stuff on them also

 

ok stupuid question you have to take the dash out to get to that right ??

 

Ya but it's easy.

 

no you just have to get the pass side of the dash to pull out a couple inches. Its really not that bad to do I had it done in a few hours. The fun part for me was the ppl that owned my truck before me had re wired the radio and put all the wires behind the access panel in the glovebox.

 

ok thanks for the help alot guess ill have to fix this i pulled a dash out of my other blazer but never thought bout trying to remember how i did it cuz im not putting that one back in im doing a custom dash maybe time for a covered dash when i put it back in lol but thanks alot

 

Ya,1st gens are "easy" compared to 94-97 and even worse the I think 01+ cores?
The newer cores are a HUGE PITA!

 

yeah heater core
