Hello,
Any idea what could this problem be? Fog Lights flash when the car is in park and engine is off. i have to leave the vehicle unlocked.

Check the locking pump module under the trunk floorboard for any water intrusion.

 

Will that cause the fog lights to flash? What does it look like?

 

Yes, it will. It is wrapped in a foam box and looks like :

I have the same problem.

 

That's the alarm module failing

 

Hello,
Where is it located in the vehicle and does it need to be replaced?

It's under the cowl beneath the wipers. Here is the thread.

That is the location of the siren, the security module is incorporated in the pump that operates the locks.
When it gets wet it goes haywire, I guess it can go haywire for other reasons as well though. Unless you are lucky they can get pricey.
You have to remove the carpet and the passenger side trunk side panels and the rear trunk liner. You wold probably have to strip all the trunk pane from the car. Others have just cut the foam block covering the pump in pieces to a
Chess the pump.
Before doing this though see if there is actually any dampness in the trunk well where the pump sits.
