My wife was traveling to Michigan last weekend in her 2006 Saab 9-7x 5.3. She called me the next day after she went to brunch and said when they got back she heard a fan running after she shut her truck off. I told her that it sometimes is normal (even though it was 30 degrees outside, so not really normal I guess), but the fan kept running until it killed the battery. The next day they tried to jump start it and as soon as they hooked the jumper cables up the fan would kick on and they could not get it to charge enough to start it. I suggested pulling the fuse so they could get the battery charged enough. She first pulled fuse 20 (cooling fan) which did nothing and then she pulled fuse 35 (J case fuse for blower motor) which she said the fan stopped after that. Once they were able to jump start the truck, they put the fuse back in. And soon as she drove away she noticed the heater (or ac) wasn't blowing air. The next stop they made the fan did not stay on after she turned the truck off and hasn't this whole week, but still no air coming from the vents with heater or ac. Is it possible that a relay went bad or is the blower motor itself the culprit? Thanks.
