No, it is not normal for the cooling fan to run constantly. I would not think it would ever come on in January. On my MP3 the fan would occasionally come on during hot summer days in slow, stop and go traffic.

When does it switch on? Some time after you start the engine or right after turning key to "On"?

The wire that feeds the ECU with temperature information from the temp sensor may have come adrift/chafed and shorted to chassis.

The wire that comes from the ECU to the fan relay may have chafed and shorted to chassis (unlikely to come adrift).

The fan relay may have arced and welded itself closed.

Easiest to check is the fan relay - just swap it with another.

Isnít the code reader socket by the battery where the positive terminal comes out. Should be yellow and black.
