If you can hear the blower motor running, you might want to check the cabin filter in the heater box. It is located on the passenger side of the blower box. There is a door that gives you access to the filter. The replacement filter is more like an accordion, with no framework. Once the old filter is removed, you can see its condition. If it has really collected a lot of junk, you might try and vacuum the box itself as best you can.2012 Versa sv
You can hear the blower motor is on but nothing comes out of vents.
It doesn’t smell like coolant, it doesn’t run hot.
Please help
