follow the link in this post, it should have a link to a StarcoolIII.PDF it also has the newer Danhard.PDF also.
Make sure that you both actually have starcool, not just one being a rear AC. They are different animals. If it is starcoolIII the first thing I would check if the blower switch isn't working is the enable switch that is usually over the left shoulder of the driver. This is typically reachable while driving. If this switch is not on, the starcool III blower switch won't work. The documentation shows the relay panel for the starcool, it also shows the fuses. Before the fuse block is a reset-able breaker.
