The relay should not squeal, it should be making a clicking noise as it toggles between on and off. Look on the chassis fuse panel for either a round or square relay box about 1 inch in size. Since it is squealing, you might not be able to feel it vibrating. Have someone run the flashers while you feel each box. You should be able to feel the relay toggling. Also, if you have the owners manual yet, it will give you a picture of the fuse block and the location of the flasher.
