Thanks for all the help. I've gotten down to just one problem, water (not coolant) leaking down from under the center of the dash, just to the left of the heater housing. Happens even when air conditioner is off. I'd appreciate any ideas. (99 SL2, 1.9).

Thanks,

guessing clogged condensate drain hose --- prob so much liquid backed up that there is more than enough to keep dripping even with the AC off.
