No am reception and poor fm reception - 2004 Kia Sedona

If the antenna is on the front, pop the hood, and locate where the antenna wire connects to the bottom of the antenna and make sure it is connected well. If everything checks out there, you will have to pull the radio from the dash, and look at the back of it. There will be a large black wire by itself connected to the radio. Push it in to make sure its connected as well. That could really be your only problem unless your radio happens to have a fault on the inside which is extremely rare. Hope that helps
