12v but bulb and led won’t work!!!

[Garth124]

Ok so I’m utterly stumped here.

Parking light on passenger side is out so swapped the little bulb, no joy,
Found a thread saying it’s in series with the led light.
Bought a replacement unit, still neither light up……

Thought pattern was there must be no power but I’m getting 10v on one side and 0.9v on the other. What I don’t get is the 0.9v is the working side! So I’m guessing my meter had a bad connection

When I turn car on the non working side goes up to 12v

So the side that shows the higher voltage is not working.

I’ve never seen this before and can’t see how this is possible. ( I’ve swapped bulbs between sides to see if new one is faulty no luck

It can’t be an issues in the ecu can it??? Surely not

Feeling like I’m being utterly dumb here
