Hi!

I am so new to this and not very good at working on my car, however my 2004 996 is flooding inside! I think it is when the AC is running, however I want to clean all drains. Please help me. How do I clean my AC drain? Where is located?

Pull back the carpet against the front firewall in the passenger seat footwell.  You will see a small drain hose connected to the bottom of the HVAC box.  Undo the clamp and can undo the hose and blow it out with some compressed air, or run some trimmer line down through the drain hose.  Also a good idea to clean out the HVAC drain pipe as well. Reconnect and you are good to go.

 

The other important drains are located to the left and right of the battery tray in the hood.

Thank you! I really appreciate your help! I think I have the issue resolved. Now I have another issue. Coolant leaking from what I think is the AOS, I think for this one I may have to take it to the dealer. I just add a little bit of coolant every day. No oil leak just coolant. Is it ok to drive it for few days adding coolant daily and watching the temperature of the engine to remain low?

Thank you!
