i just checked the operation of the rear fogs

engine is off - no lights
engine on - no lights, if i press rear fogs, nothing happens
if i press front fogs, the fogs and the low beams come up (switch in auto position)
with front fogs on, i press rear fogs, they come on
with front and rear fogs on, i turn off the front fogs, the rear fogs STAY on...

interesting....
