Hi,

GRS180 CROWN / MAJESTA AND MARK X ARE IN SAME CATEGORY.
AC Drain if leaking inside car you need to open complete dashboard to find the issue which is in between both seats gear leaver area..
The actual drain is just above the gear box (back wheel drive) gearbox there is no drain pipe coming out in any of these car.. it has very tine whole oval shape in body..
To see the location kindly check this video on youtube for further clarification.

Thanks all of you in advance as this will help many of you in fixing drain problem of ac if its leaking in this car.
If you can make any round circle hard wire and any way possible to put in their you can fix it.. or just let water dry put 5 to 10 cc of dormex or harpic it will also clear the drain but for that need to remove screen system to get in to easy access of front blower that throw air to back side passenger went remove gear location garnish and access it and put 10 cc dormex or harpic there ( do not let it go to heater side fins it can harm it)
