What else could cause water to leak into the passenger side floor besides clogged ac drain


Asked by Sep 13, 2014 at 10:19 PM about the 2010 Honda Fit Sport

Question type: Maintenance & Repair

My mother-in-law 2010 Honda Fit has a
pool of water on the passenger side floor. It
only happens when the AC is on. I took it to
Firestone complete care to have the check
the AC drain. They snaked it, but it seems to
still be leaking into the car. Any idea what
else it could be and how much it might cost
to fix

Did they blow the drain hose out with compressed air? If not sometimes just using a snake wont completely clean the debris from the drain hose.

I don't know all they told me was they snaked it

Logic dictates that the drain hole is not unplugged. Take it back to Firestone and have them blow compressed air in the drain hole.

I would get someone to blow it out just in case the snake missed something.

I will call them and ask what exactly they did. If it's not that any idea what it could be


It also makes a squeaking noise when we turn left but it only does it when the AC is on


There is a blockage in the A\C draining system. From what you have described, Firestone used a solid rod to clear the obstruction. What we are recommending is that you have them use compressed air.

Simple,answer to this question,and it is what boholmark and dandy said,blow it out with air,and just to see if they did leave that rock in there as bohlmark said,crank car,cut cooly on,let it run for about 10 minute,s,look under car,behind passenger tire,should see quite a bit of drip drip,if not they did not do there job.

Then again,may be crack in evaporator box,and if it is,then drain clearing will not help.
