i am looking 4 where the water drain for the a/c comes through the firewall? on my 2001 range rover p38a. it's plugged and when u run the a/c it drains into the drivers side floor board
thanks,
stuart

 

There is a drain on each side of the transmission. They are a bit hard to spot and you'll probably need a flashlight because they blend in fairly easily. I recommend using a coat hanger. Be careful to gently prod with whatever you use so you don't puncture the rubber. Also, be sure to have your face and body well away because it can, and likely will, gush out pretty good.

 

the plugs are located about 18" back from the fire wall. I cut a strand off some 3/8 " steel cable and soldered the ends. i started one end in the rubber plug and hooked my rechargeable drill to the opposite end. I used reverse.
