    Default See those relays?

    http://www.bmwe34.net/e34main/mainte...trical/LKM.htm

    The solder points on the board are where they fail, redo them all.

    And I've never sodered so I can't easily spot the failed ones...

    Default 3 Vs 4 Relays?

    Academic Arguement

    the fix is still the same.

    Finds the larger points on the PC board for the realys and resolder.

    Just gotta use a good rosin core solder and reflow those points.

    Some guys get real anal and desolder, but I've got better things to do...

    So should I just place a little bit of soder at the tops of these "caps", (hilighted in red)? The "broken" ones kinda look like the top (cap) of the soder is breaking apart from the base of the soder (only noticable with a maginifying glass)????

    A few point just above those in red, they correspond to the upper part of the relay and should be done too.


    Looks like you have the idea.

    I think it is a good idea o pick up some solder wick and remove the old solder and apply new.

    Your theory on the cap is correct, but it's very hard to see the failure.

    So I resolder all the suspect points, try not to add too much, just reflow a clean joint
