I was looking on bmwe34.net and reading the instructions on fixing the LKM. However when I opened the module there were only three relays. It is a 1990 535i. should I just go ahead and try to resolder the three relays that are there? It does not look like any fell or were knocked off. The are no pins in the solder underneath where the 4th relay should be and there are no pieces anywhere to be found. It is one of the inside relays if it makes a difference. Thanks in advance for the help all.
