The cabin fan speed controller in my Mrs's Subaru Impreza only works on max or not at all.
Assumption is the MOSFET cabin fan speed controller is dead.
(I replaced the motor 12 months ago.)
This is the variable type not the preset 1 2 3 max type, so it will most likely be using a MOSFET as a power resistor
Subaru want $US299 for the part but I think it includes half the dashboard.
The Mrs will not let me pull it to pieces unless I can guarantee it will be fixed with in hours.
So I need to do some homework.
This is what it looks like: (Internet photo)
This is my best guess as what the circuit is
So I need to stock up on a few components before I start the physical work
Any Guidance on circuit and/or component values would be very much appreciated.
Thanks
Greg
