2000 Volvo S80 heater fan wont work. First it wouldnt go off no matter if the dial was off or on (or the car was on or off - key in or out) . I had to pull out the fuse to save the battery from draining. Now it doesnt go on at all. There still seems to be heat though. Any ideas what it may be or even where to look for relays etc? Thanks

SOURCE: Fuel Relay

It is in the passenger compartment relay box under the left side of the dash. Along one edge there are 6 rectangular relays grouped 2 together and 4 together. The fuel pump relay is second over from the gap between the 2 groups of relays. My diagram marks it as CMI 12.
