Water in the comfort module can also be the pipe to the rear wash wipe, as mine was. Water collects in the plastic box and causes all sorts of problems. Hazards staying on, windows going down on unlocking doors via remote, locks clicking up/ down whilst driving, interior light flickering on and off whilst driving.....
Pull the carpet back, expose the black plastic box and open it up, you can then dry it out with a hair dryer, and leave it out on top of the carpet until it sorts itself out. Pull out all the plugs and clean them up as the contacts can corrode with the water.
Then it should get back to normal..
