Craig,

There have been a number of posts regarding water in rear floorboard and trunk.

The trunk is drained by simply reaching under the rear quarter panel on each side. There is a rubber drain that has four petals shaped much like a heart valve. Simply move them around with your finger and it will probably drain. If not use a piece of wire, screwdriver, etc.

The rear floorboard problem is most often cured by clearing four drains which are under the hood. Two of them are directly below the hood hinges. The other two are inboard from the hood hinges, one below the battery, the other below the fuse box. What I mean is that they are further down the firewall from the battery and fusebox. Be dilligent, find all four of these drains and clear them out thoroughly with baling wire (for city people, coat hangers seem to substitute quite well for the high tech baling wire tool).

If you will search, there have been many posts regarding the cruise control, climate control problem you mentioned. I have no personal experience about this one.

Good luck,
