Need help with durango fog lights

My 99 Durango's fog lights dont come on.  When I probe the wires to the lights it reads +12v on both wires.

Everythig else works fine.  Anyone have any thoughts?

Let me give a little more information:  I unplugged the connector and checked the continuity and voltage at both the wires.  The solid blue has +12v and the blue with black stripe has +12v.  When I turn the switch on nothing changes.  I found out that the blue with black stripe is supposed to go neg. when lights are on.  But it doesn’t.  I also tried to replace the relay.  Same result.  The only thing I haven’t replaced it the switch.  (That is a very expensive part)

Ideas?
