The dealer will inspect the blower regulator wiring harness and a new part will be installed. You won't usually pay for it.1
What’s Wrong
Over time irregularities in the crimp connection in conjunction with relative movements of the tin coated connector at the end of the wiring harness which connects to the tin coated blower regulator pin could lead to frictional corrosion. In combination with very high current flow which would occur which could lead to a temperature increase. As a result the blower regulator wiring could be damaged and could lead to partial contact of individual wire strands. this could result in an irregular current flow further overheating and increase the risk of fire.
