I have a 94 del Sol. Recently, I have noticed everything left on the passenger side floor was wet. The carpeting is wet. On a friend's del Sol, he had a disconnected tube carrying water from the air conditioner. It caused the same problem. The water tube on my car seems to be intact. Any ideas.

 

Are you loosening coolant? Check your coolant level and make sure. If your low on coolant then chances are you have a bad heater core.

 

Nah it would stink if that were the case.
I bet the air intake under the cowl is leaking. The sealer that goes around the flashing can dry up and let water come in when it rains or in a carwash. You may have the same problem.

But they don't call those cars a bathtub for nothing. Could very well be the top leaking too.

 

if it's green fluid it's the heater core. mine is oozing alittle too and will rip the whole **** out when i get a chance.

 

Probably a clogged A/C condensate drain. Peak under the dash to see where it's coming from.

 

+1. Blow some air through the top side of A/C drain tube and if clogged clean out with more compressed air or flexible blunt tip rod. Should clean out pretty easily, though.

 

Unless the OP doesn't even have a/c, I'd put my money on a seal of some sort.

 

Is say probably a seal I used to have one that did it all the time seal on the roof was bad

 

Not quite sure if you still have the problem, but I had this myself to.
My floor was even so wet, that there was a puddle of water in my car every time it had rained.

It is the seal under the cowl which is gone, therefore the water can co dripping into your ventilator shaft, into the cabin. Also see this page. https://honda-tech.com/forums/acura-integra-6/diy-fixing-passenger-side-cowl-leak-90-93-integra-2548435/

Quite easy to fix, if you have the right stuff. The cowl clips are a b*tch to get off in one piece, so I ordered some via ebay. (4 times cheaper that the dealer)...

Hope this helps.

I had the same problem, and all i did was get rid of the old sealant around the hood hinges, put a generous amount of black RTV around and ive been good ever since!!!
