DIY : How to repair fan of AC Megane II, Scenic II and more cars !

Hi all member's,

Recently I guess a problem with a fan of climate control of Megane 2 2007 years !
After check differents fuse, motor of ventilation (pulgged directly to battery) etc ... everything was ok ....
So in this car there is an A/C automatic



And with this configuration, there is a specific module to manage the power of fan !

N° 8 from the picture





After unplugged the module, I do a simple test to be sure that it was defective.
After, open the black box, just solder a bridge between two pin



Then plug the module into the car, normaly the fan of A/C works all the time and with maximun speed, you can't change the speed even with the button of control panel !


Now I order a new transistor to replace the defective, after solder it, plugged into the car everything works fine

The reference to it is :

Transistor MOSFET Canal N 60V 70A 300W TO-247AC RoHS IR (9mR) POWER MOSFET IRFP064N MOS-FET


This module is also mounted in others cars such as :
Citroen C5 C3 C2
Renault Megane 2 Scenic 2 Clio 3 Modus
Peugeot 406
Etc ....

Obviously the cars have to the Automatic A/C because with manually A/C, this module is not present !

Just for fun ! look the country origin of manufacture




Cheers !
