Hey guys I got 2000 jimmy and ive got alot of water leaking into my floorboard me and my cousin found out that is coming from the drain below the wind shield I just don't know where the drain is or how to unstop. Can someone give me directiobs

 

The A/C condensate hose is probably plugged up. Not fun to get at, it helps if you're a contortionist.... it's on the bottom of the black plastic evaporator housing. You can get at it under the vehicle, passenger side, just forward of the firewall, directly above the frame. Little black rubber nipple sticks down about 2" and it gets plugged up with debris which causes the evaporator housing to flood causing water to overflow onto the carpet. Use a plastic drinking straw to unplug the nipple. You'll probably get a face full of water when you remove the debris The evaporator is just inside the housing above the nipple and if you use something metal to clean the nipple, you might damage the evaporator. Have fun!

 

I had a buddy check for that and we couldn't find it. Although even without the ac on its doing this

 

could be a heater core, just an idea.
