Yes that is the part and is more than likely your problem. I had the same issue with the fan running at full speed with no way to slow it down. The part is next to the cabin filters and is as you described. I found a new one on eBay from a Nissan dealer and it is the same part number as the Pathfinder. The part # is 27761-70T03. The cost was way less than the local dealer. Note: I would replace the cabin filters per the manufacturers recommendation. I may have waited too long (10yrs) and as you can imagine they were filthy. The air flow helps cool this component and if the filters are clogged this "may" overheat the unit. (is this what made it fail?)
