A heating/cooling question. If she turns the fan on, heat is oppressive, blower immediately goes to full blast. She bundles up so she doesn't have to turn on heat or drives with windows down. Especially problematic, because she has a gassy dog. Guys think it's a bad heater control valve--fixing would likely cost a few hundred bucks. A cheap fix: get needlenose vice grips, and crimp heater hose to shut heat off.
