AC drain

[97 Stang]

My floor board, specifically the driver side gets very wet when the AC is running. Does anyone know where the AC drain tube is? I read if it gets clogged it will cause the AC to leak into the car. Just trying to rule it out or hopefully it will be the fix.

Well, if it gets really clogged it'll stop draining and the evaporator core will end up taking a crap on you. I don't have a service manual CD for your year, but on most vehicles, on the passenger side near where the carpet meets up with the firewall, if you peel that down, you'll see part of the HVAC housing leading to the firewall.. which is usually lower than the rest (this is the drain.) On some vehicles, you can simply drill a 1/4" hole in to the drain tube, then use a coat hangar to push debris out, then plug the hole you drilled with RTV or a plug.

Sorry I don't know the exact location.. try a google search for mustang drain tube and you may find more info.

The drain tube ends up right on the pass side exhaust - thats why it friggin sizzles when parked after driving it with the A/C on - it drips onto the hot pipe.
You'll see a water stain on the exhaust pipe, just after the pipe straightens horizontally and heads toward the back.
