I've got one lying around somewhere too. But like Dinanstu, I'm in the Toronto area. lol
I've never heard of one failing before either. Could it be a fuse of some sort or maybe one of the connections? I'm sure you checked already, but just in case. See if you can find another e36 around and switch them real quick to make sure its the DRL module before ordering another. It would suck to order a new one and replace the old one to find out its not the module that was the problem.
