Always I have the rear passenger floor wet, where have drenaje of water from A/C?

 

Do you mean drainage ? If so, there are drains in the CC box, and you should see a little puddle under the car when parked on hot days. This will be just under the front bulkhead area.

There is also a plenum chamber drain where the air enters the CC unit. This is underneath a cover at the back of the engine compartment on the passenger side. The cover is easily removed and has a grill moulded in it for the air to enter. If this drain hole blocks, water can enter the CC unit.

However, if the water is in the rear compartment, it could be a leak somewhere else. Jaguar had a TSB on this, I believe.

If you have rear air, there is an evaporator in the centre console and perhaps it's drain is blocked.
