I have had no problems with this blower until now.  I have a problem with the chute.  It neither rotates nor does it move up or down.  I have taken off the chute housing, loosened and then tightened up the gear box, and lubricated the gear spindle  I fear my problem is electrical.  Not only that... my headlights do not work and have not worked for a year or more.  Any ideas? 
Closest John Deere assistance is an hour away.  Not too bad - but the timing is another thing.
Go figure. Another snow storm tomorrow (third in as many weekends).  Ughhh!
