I need to replace the heater core on my 1993 Sable Sedan. Ugh. I know that I'll have to remove the dashboard and disconnect everything to get to it. Has anyone here done this before? Can anyone offer advice? Any online reference I find start with "Remove the dashboard..." - I'm looking for something on the level of "unscrew this screw *here* and pry this piece off over *here.* Chiltons? Haynes?

I really don't want to bring it to a shop.

Any insight is much appreciated.
