According to the manual, there are two condensate drains on the evaporator housing. One one each side and it looks like they exit thru the transmission tunnel on either side. Might want to remove the lower panels under the dash and see if you can find and check them. I usually run an old radio antenna whip up in drains (Ball end first) to try to clear them. Still, if the water was real hot, I would be concerned that you were losing coolant. I think my '86 SDL is starting to leak. It's going to get a new evaporator eventually anyway so I'll probably do both cores at the same time.
