Every time i go through a car wash or it rains the rear door light comes on afterwards and i cant use my central locking for a couple days until its dried out i guess and then everything works as it should.
Anyone know were i should be looking to fix this?

Pop off your passenger scuff plate and kick panel. Unplug the connectors there and look for corrosion/water damage.

i think its water coming in from under the windscreen somewere, stuck my head near the brake pedal and could see daylight up near the windscreen so ill put the plastics off n give it some silicone
