That little critter is your problem. It's the blower regulator. For some reason on the 140's they always go bad. They are fairly expensive $300-$400 at the dealership, $270 wholesale. Fastlane sells it for about $170, but I'm not sure if it's OE. They updated the part to 140-821-83-51. Make sure to get the new one unless you feel like changing it again in a couple of years.
