My Defrost fan does not operate. I talked on the phone to the service
manager at the dealership. He said first thing to look would be fuse.

In the heating mode, the low speed fan works, I can hear it going up 3
notches (represented by small bars) then staying the same low speed for the
next 4 notches which should be the higher and higher fan speeds.

In the fuse box under the hood,  they show a "FAN 40 Amp" at location #20
printed on the fuse cardboard inside the fuse box.  That location does not
exist in the fuse box. It goes from #18 to #21.

There are 2 other locations for fuses which I checked, a little door on the
side of the dashboard and one under the backseat, but to no avail.

Anyone knows about this mystery?
