My 99 Monty Carlo is dripping water on to the passenger side floorboard. There is also a little condensation on the floor of the garage, not the usual amount - I think. Any ideas on what to look for before I take it to the dealership and take a wallet-thrashing? TIA for any suggestions.

Hello,

There is a hose that is located on the firewall on the passenger side, it drains the condensation from the condenser, when the A/C is operational.
Dirt and debris can block that hose and the water will be backed up and drip on the inside of the vehicle.

The best way to access that drain is from the bottom of the vehicle.
Clean out any debris that might be blocking the hose.

Please let me know of any questions.
Thank you.
