My blower motor is not working. All the other functions of the vent system are working but the blower motor isn't turning. I replaced fuses, relay, and blower motor itself and it still won't work. What am I missing? What else is there?

 

Start testing for power, at the fuse, at the relay, at the blower motor harness.

Find out where the power stops.

Are you SURE you replaced the correct relay? It's behind the cabin fuse box, there are either 2 or 4 relays depending on which options you have, they're all the same blue nissan relay. Usually I recommend people just swap the relays to find out which one is bad.
