Sure the fan spindle isn't just jammed up threads to prevent the fan from drawing air over the temp sensor wire? This is quite common (happened to both of my 01s). See "ECC has no heat" in the following link<p><A HREF="http://www.freewebs.com/howardsvolvos/electricalelectronics.htm" TARGET="_blank">http://www.freewebs.com/howard...s.htm</A><p>Do be careful taking out the ECC tho. Others have fried it taking it out. See "Electronic Climate Control Not Working" in the same link.<p>Not sure if the dealer can just replace the fan. I think a new ECC + install + software = $1000.
Here's the sensor. This is the bugger. Haven't pulled the ECC to see if it is easily replaced...<p><A HREF="http://www.trademotion.com/partlocator/index.cfm?action=getJointLocator&siteid=213784&chapter=§ionids=9,0&groupid=10074&subgroupid=20011&componentid=60803&make=36&model=V70&year=2001&catalogid=1&displayCatalogid=0" TARGET="_blank">http://www.trademotion.com/par...gid=0</A>
