Rain-soaked dash

I stupidly left the driver side window down and let 2 1/2" of rain into my '04 Grand Marquis. Cleaned everything out and the car started right up the next morning. The following morning the battery was dead. Turns out that the dash lights remained on all night and drained the battery. I pulled the fuse (#21 in my owners manual... LCM for park lamps and interior illumination, Autolamp/Sunload sensor.) and let the car air dry in 90+ degree heat for the last 4 days. Those lights still will not go off when the fuse is re-installed. Will it ever dry out or is something going to need to be replaced? Anybody else ever been this careless?

Re: Rain-soaked dash

Was it just the dash lights? The LCM could still have moisture in it. It wouldn't hurt to remove it and use a hair dryer to dry it out. then see if everything is okay.

Re: Rain-soaked dash

I'm not sure where the LCM is. Is it accessable without removing the dash?

Re: Rain-soaked dash

Before doing that - is the headlight switch on? Do the parking or dome lights stay on? Door switch backlighting?

The LCM is above the gas pedal with 3 connectors facing forward.

Re: Rain-soaked dash

Problem solved. It took a week of waiting but everything has dried out and is working properly. As hot as it has been here over the last 2 weeks, I would have never guessed that it would take this long to dry out. I'm just glad that it didn't require tearing into the dash or door to fix it. Thanks for the replies.
