Toyota heater fan?

2004 toyota 4runner

fan won't blow, electronic temprature control says it's on, I can hear the flaps move as I change the function. Also the rear glass defrost does not appear to work, even though the light is on, if it's on the same circuit...

there's 2 fuses in box under the hood maked heat, a 15 amp and a 60 amp, both look good, and 2 relays marked heat.

I didn't seem to see relavant fuses in the dashboard fuse block.

Any diagrams where to start?

in the olden days I knew how to check the little resistor coils, but this electronic control has more going on, and it's too cold to just be exploring without a plan.

Thanks,

Jeff
