Blower Motor Not Working?

Hello all! Hopefully this answer will shed some light on this subject. I am the son of a bodyman ,mechanic with 40 yrs exp. and we have encounterd this problem with a 92' bonniville. After compiling information from testing the blower motor,replacing a few small parts,checking all available fuse blocks,reading the corospnding Haynes manual,and contacting the local auto elec. shop,we've discovered that the air compresser for the a.c. was throwing sparks and blew an IN-LINE FUSE.Now the real problem...tracking down the blown IN_LINE FUSE. I would suggest the corosponding Haynes, or Chilton manual for your vehilcles wiring diagrams.You can also find many auto wiring diagrams online,most of which cost money. Hope this helps.
