In the middle of trying to locate some problems with the passlock and Security lights. When I touch the battery cable to the battery (ignition is OFF) I hear a relay click behind the glove box. I'm not sure if this is normal. The body control module is disconnected. Anyone encounter this and know what relay is clicking. I'm worried that it might be draining the battery.

 

mine clicked when i installed the battery and it hasnt gone dead. i also have a 2000 4dr 4x4. so it will not drain your battery. if i had to guess what causes the click i would say that it is relay for the power outlets clicking on, and if they draw too much it will shut off
