Hi all.

Has is it stopped on all speeds?
And did it work on all speeds previously to yesterday?

Maybe fan motor has failed? Though might be worth putting fan on and trying to provoke fan with something to turn fan, think you can just about reach in through air intake , if you lie/sit on the engine? Unfortunately access limited from inside untill you strip dash...Presume if switch had failed would work on some speeds,?
I would be checking the Fan Rotary Switch to see if it has power in and out
These are a weak point on the 463 in my eyes...
Resistor Pack is possible but not usually total failure
If Switch is OK then Motor looks favorite

Yes all speeds stopped and yes it all worked before :-(
