it cant go out of order this way coz of its water resistant nature. must be some other issue, u'd better address that first then install new one.
btw, i ve drained water so many times from adv. of my car and it starts working again. water usually comes inside cabin thru the sleeves of wires and its carried all the way to adv. all u need to do is push the rubber grip back a bit and let go the water trapped inside. blow some air to dry that out.
OEM has also given a by-pass connector, in case ur adv is not working then u can plug in that connector. this connector is binded together with the wire coming down from the engine bay and connects to the adv.
good luck
