it could be a couple of things.

1. heater hoses that go from your water pump to heater core isn't hooked up.
2. heater core is bad
3. maybe theres something wrong with your air controler.

hope that helps.

check the heater blower motor and the logicon...

I have had to flush my heater core 2 times since I've had my TA and it works like a champ everytime. Just undo the hoses on the heater core from the engine compartment and hook a hose up to either the left or right (cant remember which) and flush it out. Chances are you will see a bunch of nasty crap come out of it. I'd say thats your problem if the core isnt leaking on the passanger floor board.
