Hey guys ,

I was the one who asked about the heater core now I have a fan that just blows on low ... I want to do away with the A/C that is no longer there I want to do away with the Evaporator/heater core case do I still need that to be able to use my heater? I see there is a Resistor on there is that run the A/C or does that run both A/C and heater? do I need that?...Now for a few more things... I have a Haynes Repair Manual but it does not cover things that I'm more less looking for Like Vac. Hoses to open and close heater door and vent doors ..Is that a book that shows all of the things that I'm looking for been to the Chevy Dealer and they have not a clue where to find one....need my heat in the winter,
can roll down the windows in the summer ...any help Please and why just low blower? I see Utube every one has high blower but nothing on low blower

HELP!!!!
