Morning all

Got a 2004 limited coupe doing some troubling and in the main fuse box(drivers side) are two relays if you looking from the front of the car we have on the left a yellow five pole relay that's testing good and on the left I have five pole relay in black that not testing as a five pole but test good as a four even thou it has five leads. Anyone by chance know what the left one is for and have a part number for what should be in there? The one currently in there is tyco v23134-m52-x303
