I'm not a mechanic but hopefully this will help. When I had this problem on my car, I found out that it was the "blower relay." The connection between wiring and the blower relay was corroded. Simply disconnecting and reconnecting seems to have solved the problem.

I have a 2003 Cadillac Deville DTS, 105000 miles. Similar problem except blower will not come on unless front passenger door is slammed or right upper dash is hit hard. Sounds like a loose connection, but not sure how to get to it. Any help?
