Default Identifying and replacing a MOSFET in Headlight Control Module

We just purchased a nice C4 and love it. An issue is that neither headlight moves when the lights are turned on. The lights come on - but no movement. I've taken apart the control module and found two loose wires that I re-soldered. One of the two MOSFETs on the circuit board (Board number 16509737-6) looks pretty well fried. I'm having a difficult time locating a replacement, as I'm not sure what the specs are for these - on the chip is printed "GI PA75 N85S 8638". The MOSFET looks to be rivited to the board, but it might just be a mass of solder on the back side. Can it be removed with a good desoldering? Pics attached, any info would be appreciated!
