You might have multiple issues.
As for the fans rotating, I presume you're referring to the cooling fans, not the heater blower. Let the engine idle until it heats up enough. Watch the temperature gauge. It will go up slowly and, at some point, drop a little. When it drops, your fan is running. If the fan fails to turn on, it will just get hotter and hotter, so be careful you don't let it overheat.
Regarding that one hose is hot and the other cold, I'd bet the heater core is clogged. Disconnect the other end of each hose, that is, disconnect both hoses at the engine end, not at the heater end. If you drain a 1/2 gallon of coolant out of the radiator first, there will be very little leakage when you disconnect the hoses. Hook up a garden hose to the side you called cold and you'll be reverse flushing the core. Let the hot end drain into a pail so you can examine what comes out. You'll likely find a bunch of crud at the bottom of the pail.
One more point: on my Taurus (2002) there's a short bypass hose between the heater input and output lines, so if the heater core clogs, the hot water bypasses the heater core altogether. If you have such an arrangement, you won't have much pressure on your heater core when you try to flush it since the water will just use the bypass line. Try therefore to block the bypass by pinching it with vicegrips, then turn on the garden hose and examine what comes out of the heater core.
You might have to let it flush for a while. A lot of rusty stuff comes out right away, but more little chunks will continue to come out now and then for a good long while.
