when i get to a point where i can start fixing mine i will be asking tons of questions.. first thing i will be doing is pulling ac/ heat box to rebuild it and put in a new heater core... where is best place to get a heater core... i know Detroit muscle technologies sells a good box rebuild kit...  also what is this switch your saying i need to add to the box while i got it out

I'd say check the cores first... Maybe doesn't need to be rebuilt or replaced.

The original factory evaporator core is far superior to any after market part. If it is in good condition flush it out and re-use it. On heater cores, all the after market stuff is now produced off shore in the far east. The quality of these parts varies greatly and are no where near original quality. If you need to replace the heater core because of leaks you'll have to go with an after market part but its a crap shot on quality these days.

You might also look for local radiator shops that can re-core the heater core. A used one that doesn't leak now might have a short life when put back in service.

Aftermarket (in-dash) HVAC systems are just too small.  The companies are trying to make a few boxes that fit many different old car models (to keep the costs down) and they have to compromise on the size.  Modern freon also runs weaker than the old stuff which makes it worse.

Look at a modern car's dashboard.  It's absolutely stuffed to the gills with the HVAC system.  That's what it takes to deliver the cooling we are used to.  


Aftermarket window tinting can be a real asset for cooling now.  The new stuff targets certain wavelengths better.  Like, the glass only looks 20% darkened to your eyes but it's blocking 40% of the heat/UV rays.  Some OEM cars are using it lately.

I would cover the firewall holes to prevent noxious fumes from entering the cabin.
