You need to know what fuses you need and where they go for a Ford Thunderbird 1986?

If you need to know where they are look under the dash on the drivers side they are usually labeled on the lid of the fuse panel there is a tiny hole on each side of the fuse on the back you can check it with out removing it take a test light and check for power to both sides if you have power on both sides the fuse is good if only on one side the fuse is blown if you don't have a light pull the fuse and look at the small wire in the fuse you can see if it is burned into
