Hi


There are several options fitted, depending on spec of the model.

it is easier to remove the part (one screw, an electrical connector) and compare it with the listings here - eBay heater resistor parts.

If your fan is not working, then there are also a number of failure modes to consider. Other things include damage to the BSM (engine bay fuse box), electrical connectors and the fan motor.
However replacing the controller is the quickest and simplest thing to start with.
I would recommend removing the controller and see what it looks like. Typically if your control panel has knobs, the speed controller is a resistor pack. If you have a digital control panel, the controller is a solid state (transistor) type.
Or you can just look at the connector(s) on the controller. If it has 2 green electrical connectors its a transistor type. If it has 1 black connector it's a resistor type.

I believe the resistor pack part number is 6441.Q7. The transistor type is 6441.L2.
