Heater core in my 95 Blazer took a shit today. Wanna fix it myself tomorrow cuz a new one is only $40...........how hard is it to pull the dash and how do you do it? Thanks for any help................

Nevermind..........did it in 4 hours, don't recommend the fun time I had on it though...........paying a mechanic $500 or so to do it is cheap for all the work involved...............
