Check out the images (below). Please let us know what happens.

how do i change the relay? it's wires not a plug.

Can you upload an images of what you are seeing? The relay should just pull out from the relay box.

unsure i have the right location. what i found that looks like the images was behind the glove box under the dash.

The relay should be on the backside of the fuse panel on the right side of the dash. Let me know, upload images please so I can confirm you have the correct relay.
