Anybody have an 08 Ram 2500 quad cab with hemi?

From : howard page

Q: i just bought mine saturday. i upgraded from an 04 ram 1500 quad with the slt package to the new one above that has the slt/big horn pkg. i dont understand what a switch located just above the ashtray/cup holder area does. it says light load when i push it it blinks a few times but i cant notice it doing anything else. also i looked in the manual and couldnt find it. it is located next to the electric sliding rear window switch on my truck. thanks howard. .
