The AC drainage pipe just pulls off the heater assembly, and pulls out the bulkhead.
It's likely blocked, possibly with carpet like andyfreelandy above.
It shouldn't be that hard to remove, it's just a rubber pipe pushed onto the outlet of the heater box on one end, and pushed into the bulkhead at the other. It's many years since I've taken a drain tube out, but I think I'm remembering right.Ok, i tried to drag it, should i just pull on it hard? Don't wanna break anything)
