Default Running fine but codes

I am baffled! My 2001 PT Cruiser with 104k miles runs great. Today the orange light comes on and thanks to this forum, I got the codes. 1684, 0646, 1490, 1489, 1282

After about 30 min of driving, the orange light went off.

Not sure what to think and don't know how to interpret these in layman's language.

Any help/insight much appreciated.

Welcome to the forum.

1684 The battery has been disconnected within the last 50 starts.
0646 A/C Clutch Relay Control Circuit Low Conditions:
1489 High speed radiator fan control circuit problem.
1490 Low speed radiator fan control circuit problem.
1282 The fuel pump relay circuit seems to be having a problem.

Too many codes. Just reset the computer by taking off the negative battery cable for about 5 minutes. That resets the computer and clears all the codes. See if any of them come back again later.
