My keyless entry recently starting acting odd. It will not work for weeks at a time. Then after a rain storm it will work a few times. Then nothing again. I also changed out some of the lights in my truck and had to disconnect and reconnect the battery.

Where would the ground wire be coming from? I checked the bcm and the computer in the engine compartment. All connections appear solid. And I checked my key fob at Advamced Autoparts and that's working.
