Hi spook,

I am referring to the Electronic Climate Control (ECC) system and the operation of the ECC fan (blower fan for the interior). The fuse that blows is #28 "ECC, Air conditioning" (marked ECC fan in car) and it's a 30A fuse. The term power unit comes from the ECC wiring diagram (see the last page here: http://caunter.ca/volvo960/xg14802.pdf) refering to a component mounted on the top of the climate system air box just above and left (from inside) of the ECC blower fan. When the blower fan is disconnected from this unit the fuse will still blow, but when this unit is disconnected the fuse will not blow.

I have not opened the ECC control unit and re-flowed the solder joints. I can't see how this can be the problem though as I tried a totally different unit out of another car and nothing changed. When you refer to the "relay" and "main connector", are you talking about components which are inside the ECC control unit?

The only repair work that I found in this area is on the pink/white wire that runs from the ECC Power Unit to the Motronic (MFI) System Control Module. This wire had a break that had been repaired in the past and it's insulation was stripped in one area (which I covered with electrical tape). Other then that I have not noticed and wiring problems. I've checked the wires as close as I could without opening the loom.

I'm really not very experienced in tracing shorts, so I'm not quite sure where to start. This is why I was thinking about trying to find someone locally who is experienced in working with this ECC system.

Anyway, thanks for the help so far! I'd really like to get this fan (and therefore the A/C) working again!
