Hello everyone! I have a 2005 Chevy Trailblazer Ext 4x4. I was loving it until I started having problems with my heat/air blowing I replaced the blower motor resistor and noticed the harness was melted in 2 spots, can any one point me in the right direction or help. I have been a die hard chevy fan all my life and had 1989 S-10 , 95 S-10 and never had no problems and now this.
