My name is Semin, and Iím coming from Sarajevo, Bosnia and Herzegovina.
Iím driving Renault Scenic RX4, 2.0 16V, 2002, mileage app 80000 km.
I have problem with heating fan. Fan did not work at all. I realized that problem is coming from climate controller VALEO 509355 that goes to numbers of Renault, Peugeot and Citroens.
I searched a bit and found
So, I changed transistor with a new one IRFP064N, everything worked well for a 10 minutes and fan start to work on high speed. I could not switch it off.
This morning I changed transistor again and same thing happened. It for 2 minutes and again it broke.
Sis that mean that main processor in the controller is broken??, or somebody have some different ideas???
