Meriva heating problems

Greetings MDM Community, I have problems with my 2005 Meriva, of heating the radiator fan turned on very slowly changed the module and temperature sensor, to the radiator recovery does not c heat, I already changed water pump, remove thermostat, and brushed their heads and continues to do the same the same is heated the F on the board and turns off the cool that cools it again. What else can I do?

If it turns slowly, try it directly to the battery and see how it turns, you want here is the problem in the internal or enfoinated resistance of it.

Thanks for your comment, already check that and it's fine from the fan
