As you can see you must have the proper tools for that. In your case it appears that there is a blockage on the lines to the rear evaporator - a visit to a specialized repair shop is mandatory.

I have a 94 Suburban
The lights on this truck have a circuit breaker instead of fuses. If there's a short in the system the lights will go off and you will hear a loud snap when the breaker trips and resets, it automaticly resets.

Want to know if I
You probably could, but his has to be at least a 3/4 ton Suburban to have the 454. It would take a ton of work and fabrication including things like fabricating motor mount, an adapter for the transmission (possibly), and you would have to change the computers as well since you are going from a V8 to a V6. It would take a lot of time and money, but I am sure it can be done.
Hope this helps. Good luck!

Antifreeze leaking on inside passenger side of
It sounds like you probably have a leak in your heater core. Replacing a heater core can be a difficult job. If you decide want to try it I suggest you get a shop manual to help you out. I can give you a relatively easy temporary fix that will stop the leak until you have more time to fix it or you can take it into a shop to have it done. The down side is this fix will temporally disable your heater. Wait for the engine to cool. Open the engine compartment and look all the way in the back between the engine and the firewall. Find the 2 heater hoses that pass through the firewall. They should be about 1 inch in diameter. Undo the hose clamps and disconnect them from the firewall. Get a short piece of metal tubing about the thickness of the inner diameter of the hoses. Use this metal tubing to connect the heater hoses together and clamp them using the two hose clamps. Now the antifreeze that would normally circulate through your heater core will instead circulate through this loop and not enter the passenger compartment. If you can't find a short piece of metal tubing to do this fix you can completely remove one of the heater hoses. Then take the other heater hose and connect it to location near the engine where you disconnected the first hose. Save the first hose so you can hook it up later when you do the more permanent fix. Make sure to position all hoses such that they aren't resting on any hot surfaces. I hope this advice helps you out.

I need the name of a hose I took of to replace it
Pay a visit to your local chevy dealer. They have a complete set of photos and parts descriptions at the parts window, on computer. You don't need to buy the part there unless its a pre-formed "dealer only" part.
