Just had the dealer take apart my dash to fix an AC problem. I take the car to a car wash and spray it down in the do it yourself section. Get in the car and close the door... I hear a tick pattern noise. Sounded like it was behind the air vent near the headlight switch. I open the door and the noise stops. Close the door again and it starts up again. It sounded like water dripping and hitting plastic. The car was turned off for a good 20 minutes so it can't be anything mechanical. Do you think it was my imagination? Or a potential water leak caused by the dealership taking things apart on the inside? Sorry for all the questions... just a little concerned.
