Bypassed heater core by connecting hoses together. Problem is heater blower turns on and instrument panel goes dead. Concerned, is there a relay or fuse I should disconnect?

there could still be water in the blower motor from the leak that shorts the power. you should remove the fuse for the heater until it has dried up ..or open it up and dry the inside yourself

97 K1500 passenger side floorboard gets soaking wet with really hot water. No sign of leaks in hoses or radiator and air conditioning drain is draining. Help??

Check the heater core it has a leak in it. Is the radiator losing antifreeze or a small amount at a time. Then it would be the heater core if no other leaks are showing.

Anti-Freeze found on floorboard of passenger side interior

When antifreeze finds it's way onto the floorboard of the vehicle, it's more than likely a leaky heater core is the culprit. The heater core is like a small radiator located under the dahsboard mounted inside a plastic housing. The hot antifreeze running through it creates the heat that is delivered to you whenever you turn on your cars heater. When the heater core develops a leak, the lost antifreeze seeps through the seams of the heater core housing and onto the floorboard of the vehicle. You have 2 options: You can have the core replaced by a professional, (cost approximately $250-$350), or you can by-pass the heater core by removing the 2 rubber hoses that connect to it and splicing them together. Both procedures will stop the leak, but by-pasing will leave you with no heat at all. By-passing is much less expensive than replacing. So if money is more of deciding factor than having heat, then bypass!

Im leaking antifreeze from a pipe by the firewall what is that pipe is call, u have one side going to the water pump, and the other side going to the thermostate

this should be the heater core,is the pipe itsself bad or is it just the hose needing replaced?does heat work,is the passengers floorboard wet with coolant?could be the hose bad or the heater core bad,some cars have whats called a heater control valve right there at the firewall that the hoses hook up to,it could be bad,if hoses just hook up to two pipes sticking out of firewall,check hoses first,then look in passengers floor to see if its wet,heater core is inexspensive but costly to have replaced.
