Heat & Air not working

I put in a new heater blower & a relay switch. The heat or AC doesn't kick on at all, when I start purchased the truck six months ago it did work. I noticed my heater cord leaking antifreezer fluid, I aslo changed that out three days before I changed out the other two parts i'm wrote in the first sentence. I checked the fuse in the panel box for the heat/AC, it was good. I changed it out hoping that wouldv'e fixed the probelm. The will not work in low or high. Someone said it maybe other fuse behind the glove compartment box. I take out that and didn't see any fuse their, I don't know what else to do. Please help?
