Constant Light on for wiper/fog lamp switch

[Archer04]

So I had lights out on the switches in my Dash, so I decided since they needed to be replaced I would upgrade to LED lights for the whole Dash, it is coming along nicely and taking my time to make sure I get it right.

When I upgraded the Wiper/Fog Lamp switch there was a light in the lower left corner of the switch that was on a different circuit in the card then the other two lights. I tested for positive negative connection and made the LED with a 470 ohm resistor. When I plugged the card in to test if the lights would come on. The light in the lower left came on immediately without the Headlight switch being on. I tested the wire for the positive side of the LED and found with no power on in the vehicle it had a constant 0.4 volts running to it at all times. So my question is, is this correct or do I have a wiring issue to chase down?

Any information would be greatly appreciated. Oh and when I put the entire switch back together I found that the light emits through a tiny hole just left of the Fog Lamp switch.

Do the fogs still work? If yes, you grounded the switches light. If no, check the fog relay in the under-hood fuse box. I don't think it swaps identically with the hi beam or low but you can still test to see if it's functional.
