hey i have a friend with a 96 toyota avalon and the floorboards are soaked to the point you put pressure on the carpet water comes up. its in the back and the front but not all the carpet is wet just the bottom part (not the sides or by the glovebox) I pulled up the carpet to see if there were any a/c lines or holes and there is nothing. Has anyone had this problem? Do you think its a/c related? he went to autozone and asked and they said it could be a heater core or clogged a/c line so he bought a heater core but idk. i havent looked at his heater core yet. Also i read that the heater core is behind the glovebox is this true? and how do you take the glove box out? I dont know much about toyota i drive and work on a subaru so its totally different. thanks
