Just noticed that the 99 relay that I picked up doesn't have the extra wipes when using the washer fluid spray. The original relay would keep the motor activated to give a few extra wipes after letting off of the WW fluid.
Not sure if all versions of the 99 are like this or I should be looking for another.

EDIT: I found that if I held the washer button a little longer than I normally do, then I got the extra wipes.
