Coolant Leak
I parked my 97 expy 5.4 today and had coolant leaking from the front and rear a/c condenser drain tubes.What could be causing this? I do not think both the front and rear heater cores would start leaking at the same time but who knows.

That's not good. Because like you said, the chance of both heater cores starting to leak at the same time would be astronomical. I would start by taking apart the rear one and inspecting the heater core. It's a lot easier to get to the rear one than the front one.
