Yeah I got it right. They were saying that Nissan doesn’t sell the sensor separate from the heat box so you have to buy the whole assembly 2000$. Then labor for 12 hrs at like 195$/ hr. But I found the sensor buy itself and will be taking an alternate route
I am genuinely curious how this goes for you as a DIY project in the event I'd ever need to replace that sensor. I found a 3 part youtube video that cover a repair to the Versa's ac evaporator, part of it involves disconnecting and reattaching the sensor. He says his "hack" reduces the amount of the dashboard that you have to take apart.
The area he is working on looks similar to what I've seen in my Cube, I've poked around the passenger side in order to change the cabin air filter.
