What owners wrote
I was driving my 2005 GMC sierra 1500 truck and the cab filled with smoke the a small fire developed on the wire bundle that connects to the fan blower under the dash passenger side. I had to pull over and pry the burnt connector off of the resistor / blower hook up. The fuse did not work and the connector continued to burn until I shut off the truck and remove the connector. I plan to take the truck into skillman GMC since a fuse did not blow prior to the burning of the wiring.
