cabin fan on grand picasso

Unread post by wcran »

Hi all, new here and not an expert but am an industrial electrical engineer. My daughters cabin fan isn't working on her 2015 HDI grand picasso. The fan was worn out. I replaced it and stripped the old one it was shot. Then I replaced the resistor unit but still nothing. At this point I started testing. 2 volts to cars metalwork on both positive and negative of battery connection of resistor unit. Basically no power getting to the resistor in the first place. It's an orange wire that disappears to god knows where. Tested every fuse I can find and nothing blown .All suggestions very welcome.

If you post up the VIN, which will be masked from general view, someone with access to the Stellantis database may be able to find a diagram for you :)
