this is the part responsible for the different speeds of the ventilation fan... on 4-th speed the current is sent directly to the motor of the fan. if you can find/buy another in 90% of the cases this solves the problem... or you replace the thermal fuse in the red circle.

it is situated on the left side under the steering wheel(position 8 in the picture)

Wow, that is very helpfull information as I just bought a Logan MCV 2007 with the exact same problem. Does anyone know what parts of the dashboard I need to remove to access the location where the resistor is. Would it be possible to replace it by just removing the RPM and speedmeter unit? Or the center console cover?
