Volvo Repair: AC water leaking into car, fuse panel, water leaks

Question
I have a 1990 740 turbo wagon.  The AC is cold, except water is leaking onto the passenger side.  The passenger side, both front and back are flooded.  When I make left turn, it sounds like ther is an ocean in my car and the water leaks out.  Where is this water coming from and can I repair this myself? Oh, and occasionly the overdrive will kick in on its own and not turn off.  What is causing this?

Answer
try unclogging the A/C drain which is located on the firewall on the passenger side just above the front frame rail,it is a black plastic piece just barely sticking out the fire wall.stick somethisng in the hole or blow into it with compressed air if possible.

the overdrive is probably a bad relay.the overdrive relay is located on the fuse panel behind the ashtray.remove the ashtray and then remove trim around lighter socket then you will see 2 screws remove the screws and the storage area will come out the relay is white and about 1x1x3 inch.it will be towards the passenger side of the panel.
