I think my condensate line must be plugged as I never see any water puddles under the truck as I used to see. Also, what first lead me to look, I hear what sounds like water sloshing around when I accelerate from a dead stop. Coming from under the dash.
Where is the line, and how might I unplug it?

It exits through the firewall down low on the passenger side. Once you locate it you can try cleaning it with a coathanger but compressed air would work better. Just don't be too rough with the coathanger. The evaporator is only aluminum.

I think I found it, but it's impossible to get a hand on it. It's hex Shaped (13mm), about an inch long, Black plastic. Appears to screw on/off, a bit like the old drain valve on a 57 Chevy radiator, minus the wings. It's directly behind the passenger side head and exhaust maifold. Can barely get a wrench on it.
I have to assume what I'm almost seeing is the port. I tried an air hose, but at an angle. It's impossible to get a good leak-proof connection. I suppose a real Mechanic probably has a specialized tool to do this job. Looks like I need to find him. :)

Thanks for your time, after 3 days of *$ @%& and cut knuckles.I'm out-a-here.

I don't know what your looking at but there are no wrenches involve in the drain. It's just a plastic pipe that protrudes through the firewall. It might have a rubber downspout pushed on to it. It will be a lot lower than the head. It's at the lowest point of the A/C housing.

Well, what I'm seeing is on the bottom edge of the housing, within 1 inch of the far edge of the housing. (Behind the head/manifold area) I've searched, with a mirror, the entire bottom edge of the housing, except for the area that extends over the wheel-well. All I found were two vertical 1/4 holes, one next to the 'odd' hex thing that sticks out about an inch horizontally, and another close to the point where the housing (the part that sticks out about a foot from the firewall) splits in two.
I guess I must be missing something. Or GM ran out of black pipes when they put this thing together.I sure can't find one :)
I don't suppose there are any pictures posted anywhere? Like something out of a Chilton's Manual.
