Default Check Engine Light

My check engine light is on on my 01 PT. Using the key sequence to check code, I get 0645,1490, and 1684. The 0645 seems to be the A/C clutch relay circuit, the 1490 the low speed radiator fan control circuit and the 1684 a battery disconnect within the last 50 starts. I know the battery has not been disconnected for about a year so I'm not sure about that.
Anybody have any ideas about the first two and how easy to fix?

When you turn the a/c on it turns on the fans whether the engine is hot enough to need the cooling or not. So check the fan relays and make sure the fans are running when the engine is hot or when the a/c is on.
