Ok so some u know I've been dealing with massive amounts of water on my front pass side floor when we get heavy rain...so I've ruled out the ttop and the window by running a hose down the cowl and I took the pass kick panel out and noticed it coming in from the bottom of theu blower motor. So apparently there's a drain for the hvac but I can't find the damn thing...all the pics I've found I still can't see where exactly its supposed to be and its really starting to drive me nuts...any info would be greatly appreciated cause im gonna have a rotted floor board soon lol
