The air/heat will only blow out on the feet and defrost vents, and when it rains water leaks in when you have the air on. what could this possibly be?

Your switch is not working or you have something in the system blocking the air flow divertor plate.
There is a drain in the heater core, A/C core housing that drains off the condensation that forms when you run the A/C. It is probably plugged up.

You need to check your vacuum line that comes off the tree and into the car. It should be a little black one. Check it under the dash to where it meets the vacuum plugs.

If the drain isn't clogged you might have to pull the cowl of to get to the fresh air vent and check that.

Lol, better to ask then try and guess. You should see a vent back against the firewall on the passenger side if I remember right. It's hard to miss.
