What does this part do?

I have posted this on a few forums and haven't gotten a concrete answer. I am working on my car as i type. At first I thought this was the CCRM but then I found the ccrm between the fender well and tire cover shield. It has a 30 amp fuse but there is not current coming out of this box????

Ideas?





Doing a full tune up, fuel/air filter/cops/plugs and fixing my a/c.

Well I just found out it's an Auxiliary fuse box that contains a single 30 amp fuse for the ccrm itself. The other's are not used.

It is an auxiliary fuse box, however it is related to the CCRM only in that it is the fuse for the engine cooling fan low speed operation--it is wired "after" the CCRM, between it and the low speed ballast resistor (not shown in the diagram as it is considered an integral part of the fan assembly)--here is the wiring diagram, see points "D"



It is mounted in the fan shroud.



It is there because if in low speed operation the cooling fan motor were to short it could draw a whole bunch of current and perhaps start a fire. The ballast assembly (see below) consists of a big wire-wound resistor and a thermal fuse, an almost redundancy in case the resistor gets too hot.
