how do you remove 4x4 switch on a 2007 gmc envoy
It is the blower resistor. It happened to mine and from what I can tell it is a common problem. Here is a site that helped me it also shows you how to replace it. You can find the part at AM Auto parts. http://www.sparkys-answers.com/2009/01/2002-gmc-envoy-no-low-blower-speeds.html
The neutral safety switch is located, on your 2004 Chevrolet envoy, on the side of the transmission next to the shifting linkage. The safety switch also has a fuse in the fuse box.
There is not a reset switch or a safety shut off switch on envoys.
