subeman90 Posted January 3, 2006 Share Posted January 3, 2006 Nonfunctional Heater Fan Speeds Non functional heater fan speeds are normally caused by a burned open resistor block. This block is mounted in the duct work ( for cooling purposes as the device does get quite hot.) This duct is behind the glove box and can be accessed from below after removing the plastic panel. The block will have four or five wires going to it. Submitted by Holigans Likeus Link to comment Share on other sites More sharing options...
