2007 Base,6.2,AWD, 194000
Cruise works until I use any other switch. Window, heat, fan, does not matter. The second I use other switch CC disengages. Also true for Mirror heat. When I first bought it this year WSW would also stop if I used any climate controls. My V1 Radar detector starts going crazy constantly cycling thru modes (plugged into Cig Power Out), when switches used. Is this a body control module problem? Also getting Stable Trac/ trac control Fault on info center sporadically. New battery.
Thanks for help.

Did you have the Alternator tested?

These trucks get all sorts of wonky with improper voltage.
