I have an 01 super crew with water leaking in cab out of floor vents when a/c is running. It has caused the blend door motor to crap out. does anyone know where the drain tube is located because I think it might be plugged. Any help or other ideas would be greatly appreciated. I have already replaced blend door motor on my wifes 01 expedition. No fun

 

The drain is a plastic nipple that goes through the base of the firewall directly under the evaporator inlet tube (usually). Certain vehicles also have a hose elbow on the nipple to direct drain outflow away from sensitive components.

You will have to get under the vehicle and look above/around the exhaust or drive train to see it.

Just look for a rubber drain tube coming out of the passenger side of the firewall under the hood. If it's not plugged it may have just come loose under the dash below the evaporator.

 

I guess I type slow

 

thanks for the quick replies
