Default 2017 RX Blower Motor not working

The blower motor for the AC/heat/defog stopped working. Can someone tell me where the fuse is located for the blower motor? I’m hoping the fix is that simple but has anyone else experienced issues with the blower motor that may have some thoughts?

Typically a fuse does NOT just blow. There are underlying issues causing a fuse to blow.. Typically..

Your fuse diagrams are on the fuse box covers inside engine compartment and under steering wheel.

There are 2 fuses and they are in the fuse box under the hood. They are marked PTC HTR No.1 and the other is HTR. Both will have the number 50 on them (50 amps). It's a good idea, if possible, to determine the cause of a blown fuse before replacement. Let us know how you make out.
