How To: Clean your AC drain if water is spilling into your car

Clean your AC drain if water is spilling into your car

This next tutorial is going to be showing you how to take care of a problem that is very common amongst drivers. If water has ever spilled on you from inside your car, it's probably from your HVAC. When you use your A/C, condensation builds up as well, and this usually goes down a drain. But if it gets clogged then you might have a problem.

This tutorial is going to show you what you need to do in order to clean out the clog to prevent any accidents from taking place again. So good luck, be careful, and enjoy!


ok, So my ac line is not clogged. Matter of fact it runs out very fast under the car when the ac is on. I still have wet carpet on the floor only, on the driver's side and the back seat driver's side floor only. No water under the driver's seat, just where you put your feet. Stumped here?

What became of that mine is doing thatvnow

I have this exact problem. It stinks in my suv after running the air. And water is only driver side back seat floorboard. Did you figure out why?

my car 2003 Impalia the blower motor keeps blowing fan resisters leaks water on floor on passenger side when there's lots of rain when car is parked no leaks when can't find any leaks anywhere

I have the same issue with my Volvo S 40 would I be able to do the same thing I'm getting water backed up into my driver side back floor panel the water is draining constantly

Looks easy enough. I have my 2006 Jeep commander up on ramps and the air hose in hand. Now if I could only find the drain line. Please help!!!

Fixed my 2013 GMC Terrain straight away! Thank you for posting. For those of you with a Terrain, the drain tube is located on the driver side, made of black rubber and sort of looks like a smoking pipe stood vertically against the fire wall.

Well when your a/c is clogged then you have mould in there. It's a health hazard and causes a very bad odour when the a/c is turned on or off. You should talk how to clean that problem but please don't tell us to use just these cheap sprays...

Change your cabin filters. It will also help with odors and the drainage

Is there a way to clean the drain hose out if you don't have an air hose to use?
