2003 GMC 2500HD. My truck had been parked for several weeks. When I started to use it, the key FOB wouldn't work. (Replaced the battery and reset the system. Still no go) Then once I got inside, none of the power equipment would work. The driver side lock works, but does not effect the passenger door. I know there is a TSB on this issue, but wonder if anyone here has found a fix. Thanks
