Hi guys, first time forum user here. I have a 2007 200 series landcruiser wagon and the aircon is leaking into the passenger side footwell. Does anone knownwhere the drainnpipe is? All i can seem to find is the small black plastic blockbunder the aircon that goes through the floor and comes on top of the gearbox. Is that the only drain hole? Thanks in advance Quiny
