Problem Point 1.3mjet radiator fan always on

[rebirthafterrevenge]

Hi I have a problem on a punto 1.3 mjet 2004 . This car has no air conditioning and have been replaced the body and the ecu (taken from a car with air conditioning) now when the car is turned on the cooling fan motor , of course, I have these errors in the engine control unit P0530 - pressure signal conditioner , P0645 - command rel? air conditioner , P0481 - command the fan to high speed.

This defect of the fan always on ? due to the lack of air conditioning?


Thanks to all of you.

trying on a 147 1.9 jtdm to remove the pressure switch refrigerant and also the connector for the electromagnet of the compressor , nothing happens!! the fan is not part of it! could it be the fact that the point does not ? designed to have the fan on the second speed? and then is partile the first speed?? I'm confused! THANKS
