First, anyone have experience with plugged up drain holes in the doors? Where are the drain holes located? If they plug up, does that lead to water on the floor inside the car?

Second, the power door locks do not work. I am reasonably sure the fob's battery is working. Is there a relay or fuse for this?

 

Powerlocks on my 996 are on a fuse. if you look in your ownersm manual it will tell you the location of that fuse and most importantly what else if anything is on it. You should have a tool in the box to pull out the fuse. You can see if it is blown by looking at it. You will have extra fuses in your box. This is based on my 996 experience.

I cannot help you woth your other problem.
