Water puddles on the driver side only... what's going on?

After driving for a while, I got out and saw a puddle of water only on the driver side. Is it condensation from the AC or heater?

Is there a fix for this, or is this something I have to get used to?

I used to have this problem because my sunroof drains were blocked.

I had the same issue. Since then, I’ve been cleaning the drains regularly.

How do you clean yours?

@Zechariah
I use weed whacker line or wire to break up any blockages. Just carefully feed it through the drain hole. Then I pour some water into the tray to make sure it flows properly.

I’ve had this happen to me twice because of blocked sunroof drains. I took it to a shop both times, and they probably blew air through the drains to clear them for a small fee, maybe $20. You could also find videos online to try clearing it yourself.

To check if this is the problem, pour water into the right-side drain and see if it flows out by the right tire. Do the same for the left drain. If it’s blocked, water won’t come out.

@Asa
Blocked sunroof drains can cause this issue.

You can try using a clean dipstick, the one you check your oil with.

Also, spray Windex to clear out the debris.

Check the door seal too. It might be cracked or dry.

@Asa
Check the seal! This is a common issue in cars with sunroofs. The drains can get clogged or the seal might fail. There are good tutorials on YouTube to help you flush the drains.

Is the picture I posted showing the drains?

Get the moisture out as soon as you can. If you have a dehumidifier, run an extension cord through a cracked window and leave it running for a day or two. You can remove most of the water with towels or a shopvac.

If the carpet stays wet, it can cause mildew, which is hard to get rid of. Wet floors can also lead to rust in the floorboards. Even when the carpet feels dry, there could still be moisture against the metal parts of the car.

Do you have a sunroof? If so, try cleaning out the drains with some string trimmer line.

Another possible cause could be leaking weld seams. I used Flex Seal putty on all the seams under my doors and hatch. It fixed the problem, and I haven’t had leaks since. I don’t have a sunroof.

Can you link the putty you used?

I just got Flex Seal Putty (black) from Walmart. It came in a white plastic can with a black screw-on lid.

Thanks! I’m thinking of doing my back hatch and maybe checking the doors for leaks too.

@Teegan
No problem! Just make sure to clean the area well before applying the putty. I also used rubbing alcohol to make sure the surface is clean so the putty sticks better.

Thanks for the tip .

I had the same problem with my '09 car. It was caused by a problem with the door seal, and water would leak in during heavy rain. I suggest parking in a place where the car isn’t exposed to the rain, letting it dry with the windows cracked, and using a dehumidifier or Damprid to help with moisture.

It could be a clogged sunroof drain or a leak in the vapor barrier in the door. Water can leak between the vapor barrier and the door’s metal, but it won’t show up outside because the rubber seal keeps the water in. You can fix this with Amazing Goop’s automotive adhesive, but make sure to get some replacement trim clips because they might break.
