It's the blower control module. Common failure item. It bolts into the top of the plenum on the firewall under the hood, just about in the center. I believe the plug is L-shaped, or possibly is two connectors that make up an L-shape. You can use a junkyard part to fix it, but buy two just in case you get a bad one. Should be able to get it at a U-pull for around $10. Easy fix.
