i had 3 but now i have 1 as one died and one disappeared. the remaining one is my mum's cousin; i see her sometimes, usually at family gatherings, but other than that there don't seem to be any extra special godparent treatments .
There is a control arm that shuts the flap in the mixing box to control where the air goes. The hook either came off the arm, or it is controled by an electrical switch that has gone bad. Get a Haynes repair manual. $20 well worth it.
