2002 Buick Century Q&A
2002 Buick Century Question: Air Conditioner is filling the car up with water on the passenger side.
It is coming from the air conditioner up under the dash board and running under the carpet. I pulled the seats out and lifted the carpet back on the passenger side today and vaccuumed out about 8 gallons of water. I watched the sponge under the dash/forewall pad drip with the A/C on and stop with it off. Car does not leave a puddle underneath (outside) when A/C has been on like most cars. Is there a drain hose somewhere that may have come loose? I need to stop this so I do not rust the floor out. - outhouse
This is a common problem this time of year. You will need to get under the vehicle and look for a short plastic tube coming from the black case at the firewall on the passenger side. Carefully insert a piece of wire up it about 2-5 inches. Most likely you will get a rush of water so you might get wet. If you have a shop you regularly get service done at I'm sure they will clear it inexpensively if not for free. - Justin Case Auto
