Air Conditioning problem
2006 Hummer H3 6 cyl All Wheel Drive Automatic 50000 miles

There's a sensor inside the housing of the blower fan under the dash. It went bad, so I replaced it. When I pulled it out the mateing connectors had melted. Why isn't this line fused properly? Is there a recall? Now it has gone bad again 6 months later.

Thanks,
Kevin

It melts because of the high resistance at the poor connection. Ideally the terminal should have been replaced. It is surprising, with the number of these seen, it has not had a service bulletin. You can either get a patch harness with leads, that replaces the connector using crimp and seal connectors, you can get an HVAC extension harness, or you can get the red connector body, lock, and a new terminal to crimp on the wire.
