1999-2020 Chevrolet Express Van/GMC Savana Blower Motor Speed Selection Troubleshoot
Experiencing an issue with the blower motor speed selection on a 1999-2020 Chevrolet Express Van or GMC Savana?
The most likely problem is the blower motor resistor has failed and will require replacement. Another common problem is the electrical connector/blower motor resistor pigtail connected to the blower motor resistor may have a short causing the socket connection to melt.

The 1711755 is a replacement blower motor resistor pigtail that comes with the same color coding as the wiring harness and includes heat shrink over the butt connectors. All you need to do is cut the old pigtail connector out, match the wire colors together, then crimp the lines. Finally, using a heat source, heat the heat shrink connectors to waterproof them.
