Hi there. My friends '02 325xi blew up the radiator fan conveniently right after i fixed the carrier bearing. I'm sourcing a new fan, fan clutch, radiator, shroud, expansion tank and thermostat housing with thermostat, but there were two electrical connectors on the left side that go blown up as well, can someone point me as to what these are supposed to connect to? I'm thinking maybe the auxiliary electrical fan, but I can't tell.
