I have a 2008 G6 GXP coupe. The driver side power window switch keeps going out. I have gone through 4 of them in the past 2 1/2 months. All other electrical systems work fine. The passenger side window switch, sunroof and power mirrors all work. The windows work fine one moment and then it just stops. I don't hear any shorts or pops. Has anyone else had this problem and if so, how did you resolve it? Thanks in advance for your help.
