Hello, and welcome to FixYa. Please allow me to assist you.
Yes, you can do this yourself, and save yourself the costs of a technician doing it.
What you have is a clogged AC condensate drain hose.
When the AC is on, the AC system removes moisture form the air in the cabin, and drains this moisture out onto the road surface.
What you need to do:
Open the passenger side door, and have some towels and a small bucket ready. Pull back the carpet in the passenger side footwell, and, once the carpet is pulled back, you will be looking for a small black rubber hose that goes from the heater box, and pokes thru a rubber grommet in the firewall, towards the engine. Pull the rubber hose towards you, away from the firewall grommet, and see if the outer end is plugged up with mud. If so, insert a suitable thing, like a pencil, into the end to unclog it. Be prepared for about a quart of water to drain from the hose into your small bucket.
If the water does not drain from the open end, pull the hose off totally, from the bottom of the fitting on the heater box, and runs a coathanger thru it, to release the blockage, and then flush it out with water. Note that when you remove the rubber hose from the heater box fitting, water will drain out onto your carpet. This is where you need the towels.
I hope that this helps you out, ans saves you the 70 dollars most places would charge you to clean your drain hose.
