Welcome to AF !
I would stay away from the flush !!!
ITs not good for high mileage cars.
IT washes away alot of clutch material , and puts it in places it shouldnt, valve body etc.
I thought the manuals said every 40-50k niles to change the trans fluid and filter.
But it would be good to get those changed.
On the wet floor your drain for the HVAC could be leaking, heres a pic.
HVAC drain
its the curved elbow on the right, its located on the passenger side fire wall.
If you hav a sunroof, it could also be a roof drain leaking because its plugged or the hose(s) are cracked.
Had this happen to me.
With the fog lights its tricky gettting your hand back in thier but it can be changed with out removing any lower front panels.
Though it does make it easier to loosen the cover right under the light housings.
just turns left to loosen right to tighten the bulb(s).
Hope that helped !
