See those round circular crack lines in the center of the
solder joints indicated in this pic? Thats what your looking for. any small lines like that usually a complete circle constitute a cracked joint, they are most likely on areas where the relay's are joined to the board since a relay actually shakes and vibrates when actuated which tends to make the crappy solder joints crack http://www.bimmernut.com/%7Ebillr/im...cks%20copy.jpg

I took the general module out of its case and warmed the board with a hairdryer. When I reinstalled it everything worked fine. How do I diagnose what solder joints might be cracked in order to repair it?
