Thanks guys,
Yep it's an '84 380SE Midnight blue with grey interior and 182,000 miles.

I'll check this out today. I'll install a fuse to the Aux pump also. Sounds like good cheap insurance. I was sure that Aux was what I heard running. The fan has a mind of it's own. just comes on at will and runs a few minutes or seconds and goes off. That is why i think the fan motor is fine just electronic to and frm? are messed up. I just went and grabbed some coffee and though not really cold here this morning, the heater on low did heat the cabin(front anyway ) without the fan. I'll get this old girl sorted out. I think she likes being driven after her "vacation". I think I'll look for a rebuilt or good used CCU unit as I don't trust this one now. However all the solder connections are fine, not cracked, just the two traces were fried.
