Mark, N59 is in the right foot well, but I would not worry about it for now. It is a power consumer, not the source. I think you need to check your fuses again. To check fuses you need to measure voltage between the fuse holder and chassis ground. Measure on both sides with ignition ON. If the fuse is good you'll see same voltage 12VDC. If the fuse blown, you'll see 12VDC on one side and 0 on the other. Also, go back and double check fuses on the Base module. You need to check continuity on them as you can't get to the holders to measure voltage. Do not rely on visual inspection only. If you find all fuses good I'd suspect the Base module. Maybe burnt trace inside?
