An association for tradespeople lists all bazaars in Istanbul. You may select a day and see the bazaars held that day. Nearly half of them have links to Google Maps as well. By the way, consider that the Turkish word pazar means both bazaar and Sunday.
There are 50-60 bazaars each day of the week, so it is hard to tell which are better for tourist attraction. I see several blogs listing the best bazaars, but they are in Turkish.
Maybe I can try to compile these lists into one list (by alphabetical order).
