Did you 'burp' the cooling system and get all the air out? It sounds like it has an airlock.

Turn the heating to FULL (very important). Remove the radiator cap, (as opposed to the reservoir cap, but remove that too). Start the engine, and keep topping it up. When the thermostat opens, there will be a surge or drop in level. Continue to top up. Check the temperature gauge in the car to make sure you are at full operating temperature. Turn the engine off, top up to the brim one last time, put the radiator cap on. Top up the reservoir, and put the cap on that.

A car radio needs power which you say it has. Also needs an antenna hooked to the radio. Next it needs hooked to the speakers. If you have all of the above connected and still doesn't work, look for another radio.

The valve that allows hot water into heater core is stuck in the closed position. It needs to be replaced.

If the compressor is the problem A/C should work. But I work with idiots. I replace the compressor, expansion valve and dryer. And clean the system out. They replaced the compressor. then the expansion valve. then did it again after they clean the lines out, Then again, because the dryer held to much metal from the compressor going bad. And yes, you can bypass the heater core. But if the blend door actuator is bad, it won't be cold.

Water is probably coming from behind the dashboard. It will be from the windshield or the firewall that water is getting in.

Don't put a larger fuse in; you could burn up the wiring. You need to look at each item that the fuse protects and see which is shorted to ground. You need a wiring diagram and an ohmmeter.

A quick check to see if it is the relay is to turn on the AC, the fan should come on while the AC is on. If it doesnt you are more than likely going to have to replace it.

Check to see if the Control cable from the transmission got hooked back up to the throttle body.
