Replaced plastic housing for $100. Recommend buying the whole assembly though. Cost a bit more but you would be done in 15min. When you just replace the housing, you have to disassemble the old one very carefully to reuse several parts that do not come with the housing. A lot of fragile plastics. Plus, make sure you have GooGone and 3M thin tape handy; you will absolutely need it. Again, buy the whole assembly and save time and headache.
