How do I access the air conditioner drain

Good idea is to drain the coolant from your radiator, then replace the hose that is leaking and then fill with coolant to the proper level. Drive your car and have heater running to remove any air in the system.

If you you are running it in Defrost the A/C will turn on to dry the air thus turning on the Rad fan also check to see if your A/C switch is turned on.

Your drain may be clogged. The drain comes out of the firewall. You could try using something flexible to snake the drain or bring it to a shop and have them look at it. I personally use compressed air to blow the obstruction free.

1. Air conditioner evaporator drain hose is blocked. Clear the drain hose where it exits the passenger compartment.
2. Air conditioner evaporator drain hose is disconnected. Secure the drain hose to the evaporator drainage tray under the dashboard.

recommend cking the drain holes,should be 4 drains in the corners, sometimes you have to clean out all drains, usually they clog in the bottom.dirt,trash,etc.builds up and restricts or stops the flow then it backs up and leaks into cockpit area.

The air conditioner condensation drain is under the hood not inside the car. The fluid is probably a leaking heater coil. It is located on the passenger side firewall.

You need to clean the drain out as your first step. This is accessed by raising the vehicle on a lift then using something like a coat hanger pressed into the drain hole at the base of the firewall next to the transmission bellhousing on the passenger half of the vehicle.

Three possibilities--the windshield is leaking water, the heater core is leaking antifreeze (should smell like antifreeze), or the air conditioner evaporator (near the heater core) has a plugged drain tube and the water condensed out of the warm air is running back into the cab. Hope this helps!

That drain line is for the box that holds the air conditioner evaporator and the heater coil. It seems that your heater coil has sprung a leak and the leaked fluid is coming out the drain. You have to replace the heater coil, which on most cars involves removing a lot of the interior equipment, including the dash board on many cars. A job best left for the repair shop unless you're very adventurous and patient. Even then you will have to take it to a shop to have the air conditioning system recharged.

The issue is condensation from your air conditioner not properly draining. This is usually caused by a damaged, or clogged drain hose. The condensation is supposed to drain outside the vehicle by way of a hose on the firewall area.
