Iam needing help to locate and how to repair a turn signal flasher for a 1997 Mercury Mountaineer?

well you can not repair the flasher it is either good or bad ! if u have owners manual look under fuses to locate it ! it is either a square black thing or it could bo a round silver ( size of a soda cap ) and should say flasher on it... most of them are located under the dash area above the brake pettle. hope u have luck findin it
