Toyota Repair: leak, c drain, drain tube

Question
Hi there, My 2003 4 door tacoma leaks water into the cabin, somewhere near the firewall. The water seems to travel from there to the drivers side door.

The clue that may help determine the source is that it doesn't leak when it's parked pointed down hill.  Any insight would be appreciated.

Answer
This is usually due to a clogged or disconnected a/c drain tube, pull the carpet back on the pass side and check the drain hose, make sure it's connected on the bottom of the evaporator housing and exits through the firewall, pull the hose off at the evaporator to see if any water comes out of the housing, if so the hose is clogged or it may just be disconnected.
