Default A/C drain plugged?

After driving my '15 with the A/C on I notice it doesn't mark it's spot like my GM pickup and SUV does when shut off. Is it possible or even probable that the drain line is plugged? The carpet is not wet. I think it might be after cleaning the mouse crap out of the air ducts this past spring. Where do I find the drain line and how do I clean it if it is clogged? I get that awful smell for a short time thru the vents after turning on the fan . Thanks!

The drain is a rubber elbow on the firewall below the coolant reservoir. I can post a diagram from service manual when I get to my laptop.

I noticed mine doesn't drip on the ground, but I do hear sizzle like it is dripping on the exhaust. I've only had mine for a few months, so I'm nowhere close to an expert, but maybe its supposed to be that way.

Yup - dripping on the exhaust is normal.

The gm engineers did not want any fluids dripping from a Corvette so they positioned the exhaust to vaporize the ac condensation.
