how do i clear a overflow drain, it leak's water all over the passenger floor when ac is on. i tried to pull blower box out from behind glove box but it hanges up under dash with what i can see all mounting screws and bolts out. i dont want to take out upper dash out too. i put up on ramps and went under car to see if there was blockage at the tube on firewall and it seems clear. what can i do to fix this problem.

Hi taub4126,

The drain hole on which the tube is attached might be clogged. Did you try to clear it by pushing a wire through it?

From under dash, at lowest point of evaporator, check if the tube is kinked.
