Auto Air Conditioning & Heater Repair: ac leak, drain hose, looka

Question
my ac is leaking water inside my car what causes that

Answer
The drain hose or hole in the bottom of the evaporator case is plugged up just like your kitchen sink.

Crawl under the vehicle with a flashlight and looka for a small tube or hole in the black plastic housing between the engine and the passengers compartment and you will see a small rubber hose or just a plain hole about the size of your little finger. Just take a PLASTIC flexible straw and poke open the hose or hole and the water will run out  onto the ground.

This will in most cases fix your problem.
