this is a EURO/ECE LKM = 4 relays, US version has only 3 relays as no rear fog lights

If you look closely at the above photo you will see that the relay solder connections have fractured and are not really soldered in any more. What you have to do is reheat them with a decent soldering iron and add a little more electronics grade silver solder. You need to add more solder as the flux in the new solder will help re-establish the connection so your LKM will work again. You can be anal and remove all the old solder and re-solder each connection but it's not really required. (I don't like solder suckers)

Look closely at the relays and be sure to touch up all the contacts (on both ends of the LKM)

If you haven't ever soldered before then Google it. Its not hard
