Can someone help me figure out why my Driving Position Memory System (DPMS) stop working. I doesn't light up and I don't know whether a fuse is blown and if so, what is the fuse number and which fuse box is it located in (under the hood or the interior). Also, my driver-side mirror adjust in instead of down when I'm in reverse. I just the mirror part replaced because it was defective. Could this also be related to the DPMS?
