I own a 1991 Honda Accord Ex that has developed a curios issue. I was cleaning the interior this past weekend, and when I pulled up the driver's side floor mat I discovered a thin puddle of fluid covering the hard plastic piece of the floor. The fluid is odorless, colorless, and tasteless (I'm 75-85% sure its water). I know Hondas have a reputation for being leaky, but the odd thing about this is that the fluid/water appears to be welling up from underneath the carpet. Its happening at an exceptionally slow rate; after cleaning up the original puddle (which had to have taken at least 4-5 weeks to form), I can only detect a few persistently damp places in the carpet around the edges of the hard plastic piece on the drivers side floor. The car had been in the shop the day before I discovered the fluid, maybe that has something to do with it? Is this just a little old car quirk, or is it a symptom of a more serious problem?

 

Its likely a leaking clutch master cylinder. Look at the push rod where the boot is. Also look at the master cylinder reservoir. It would be low.

 

I see. In its current condition, is the car safe to drive? I was planning on taking a 4 hour (one-way) car trip to visit family later this week. Would I be able to do so without risking damaging the clutch master cylinder or a major breakdown?

 

Since we're talking about the clutch, I would also add that my vehicle has an automatic transmission.

 

what was the car in the shop for?

 

It had to get the VSS module, Temperature sensor, and and engine mounting bracket replaced.

 

If its an auto it has no clutch lol .. you will need to look closely

 

Whoops, my bad. Anyway, what are the chances that it could just be water? Are there any essential fluids that have no smell, color, or taste?

 

Does it have a moon roof? Check the drains.

Hmmm....I do have a sun roof, and the location of the drains makes sense. I'll be sure to check that out, and report what I find.

 

Glad somebody asked the question about the moon roof.

OP- not sure if the 4th gens are like the 3rd or not. For the drivers side front tube you might have to move the fuse box to get a good look at the "connection" between the tube and the vent/valve part.

IMHO, what happens is the vent/valve part gets clogged, this allows water to back up and then start to leak at the connection where the tube and vent/valve join. Eventually that connection will "pop" out.

To get to the front vent/valve you will have to remove the inner fender - or at least remove the clips/screws towards the backside of the car to gain a view behind it. I use something like "weed eater line" to clear/clean the vent/valve.

Then if one is leaking....might as well check the other three.
