Look for a black box about 3/4 to 1" think and 2 1/2 to 3" wide and stick you finger on it while the flasher is running. I just had to replace the one in my wife's van and it was integrated into a unit with the low high beam and daytime running lights. Went from being a $15.00 +/- part to a $125.00 part. I think with a bit of ingenuity and a screw driver or two one may be able to seperate and replace individual components. Of course YMMV.
