hello, I own a 2003 gmc sierra 1500HD. It has stock power fold mirrors. I purchased after market power fold tow mirrors. However they are not working correctly. I figured out the gray and brown wires are the fold pins. The new mirrors fold wires are in the correct spot however they will only fold one direction. If i swap the wires they will fold the other direction. So the fold out button is the only button that works on new mirrors. Works fine with stock mirrors. When I push the fold in button the mirror glass moves like the stock does but never does fold in. Any ideas? Thanks for the help.
