Carpet wet with water on passenger side

[99suburban2wd1500]

I have wet carpet on the passenger side front seat. It seems to be water, it does not have any antifreeze odor. Does the front a/c have a condensate drain somewhere that could be plugged. I had the same problem with the rear a/c and also in my '00 vette. I'm hoping it's just a plugged drain tube.

Yes it has a drain tube that if pluged overflows in the passenger side front seat. Dave

Ok, so where can one locate the drain tube?

90% of the questions answers can be found by using the search of the fourm. I happen to know about the DRL diode but did not think of it when I pulled the # 15 fuse. The drain tube runs from the heater box (inside and under the passanger dash) out the fire wall ( under the hood by passangers feet. Dave

I guess you have realized by now it is not an air conditioner leak that is flooding your passenger seat pan. I have the same problem on my 1999 suburban. I have not been able to solve it however I do know it has to do with water getting in through the door. I have taken the door skin on the inside off and ran water from a hose on top of the car with the door shut and watched it fill up. The only fix I have right now is to MAKE SURE you park with the back of the vechicle LOWER than the front of the vechicle. This will keep the carpet dry. I know this is not a good fix. If you learn something better please let me know.

I had the same problem with my 99 Suburban. I located the condensate drain on the firewall side and noticed water coming out. I figured it was ok. But then I looked at it again with the engine running and noticed water was being blown back through the firewall opening and down the floor pan (not back into the drain). I surmised that there was originally a short drain hose that attached to the nipple coming through the firewall. I fabricated a drain hose out of an old piece of premolded heater hose and attached it to the nipple (which was quite a daunting task-that thing is not easy to get to). Problem solved.

Thanks for the reply buftfan. I suppose the amount of "blow back" to the inside might be affected by the recirc setting, with a recirc set to yes for max cooling causing lower positive pressure inside the truck and thereby allowing more "back flow". I will definately pursue reinstalling a drain tube.

***I had the same problem and after 7 trips to the dealer service department and being told it was everything from a faulty drain tube to several unbelievable theories, it turned out to be that the windshield was installed incorrectly at the factory and wasn't sealed properly along the bottom of the glass on the passenger side only. After they figured out what was wrong with mine, they had 2 more suburbans come in within the next month with the same problem. They just took the windshield out, and reinstalled it and haven't had a problem since. This would only make sense if your carpet is wet after driving in rain, however!!

On my 97 Suburban I had the same problem. It turned out to be one of the screws holding the plastic cowling (to rear of hood) was pevetrating the climate control air box. Poor design. Remove the cowling, apply new sealant to the screw that goes through the sheet metal and into the air box, reinstall the cowling and the problem should go away. It did for me.
