Hi, I had the same problem with my 2005 Silverado. The fan stop working completely. The wiring harness connectorwas melted. I replaced the resistor $68.00 & the wiring harness connector $20.00. Now 1-4 works. High 5 doesn't. Someone told me that there's a fuse under the hood that is blown. I'm going to check NOW!

Most likely the blower motor resistor. It's mounted next to the blower motor under the dash. Also check the 7 wire plug going to it, GM had a problem with that plug, and the wiring getting hot and melting. The plug is $68.00 from the dealership. One of my customer's car had the same problem.
