BLUE is what you are looking for. There are two of them running in to the furnace. Before you disconnect label what they connect to. Im not sure that is needed but it will make you more comfortable when you put them back together. take the two blue wires and put them together. If furnace works then tstat is faulty. Most likely it won't and yu need a sail switch or freon would be second choice. Hope this helps you
