New, and unfortunately with a water problem :-(

Hello!

I have been hoping to find a Cobalt forum for some time now as my fiance has a fairly new Cobalt. Unfortunately, now I found one right on time, as we have a pretty wet problem I hope someone here may be able to help us...

This last Saturday, TS Hannah came through our area and dropped a good 24 hours of heavy rain. We had to be at an appointment that afternoon, so we braved the storm. We drove through some significant water... nothing considered flooding, but enough to cause those huge splashes and that slight hydroplane effect when driving through water that isn't draining down the storm drains quick enough.

By the afternoon, the sky was blue as Hannah went north. When she was driving home, however, she could hear water swishing back and forth when turning the corner. When going uphill, water came out from under the glovebox area (where the black cylinder - fan? - is located on the passenger side by one's feet.)

She laid some towels down to absorb the water. Today (Monday) it happened again.

Is it possible that the water on the road got up into the car and is sitting in there somewhere? Maybe the water drains out when her car is on an incline like a hill?

Her Cobalt is only just over a year old - she bought it new in June 2007 and it only has about 12k miles. Surely its still under warranty?

What can we look for re: the water? Should we be worried? Does anyone know where the water might be sitting? Does it make sense that its a result of higher water on the road, or is it something else with a strange coincidence?

We appreciate anyone's feedback, which might help us before we run to the dealership. And thanks for the opportunity for being able to say hi as a newbie

12K miles.... take it to DEALER. Obviously don't tell them you drove it in the storm but let it sit during the storm. The heavy rain sounds like it got down in the blower motor housing and that is where you are getting the slushing sound and water leaking. But, DEALER... the car is 100% under warranty.

You're right, dealer is probably the way to go with a warranty. But I wonder, will we never be able to take the car out in heavy rain anymore? Seems we may have to be extra careful to avoid this type of problem when water sits on the road, yes?

I wouldn't say they can't sit in the rain. It is possible with the heavy downpoor you got that it may have just over ran the designed drain line for water. That or you may have just hit some deeper water than you expected and it came in through the evap. drain in the firewall. If that IS what happened that would explain why you got water inside your heating/cooling housing.

Would that be covered under our warranty?

If the problem is a symptom of a defect/problem it would be. I this case you may have a blocked drain -- the AC system is always getting rid of moisture and there is a drain that gets rid of the water -- if it is plugged you would retain water in the AC system and this would sound like it's in the glove box area. Aslo, since the air filtration system is under the plastic plate above the firewall the heavy rain fall could have let so much water in that coupled with a plugged drain you'd have that problem for sure.

The drain is in the firewall -- look straight back from the #1 sparkplug (farthest left as you look at the engine from the front) then follow that spot straight down the firewall about 15" you will find the square plastic drain pipe. Make a small hook of some wire and see if you can find any debris. If you poke something into it and water comes out you probably have a stoppage. The design is a little inane as it is level with the ground (instead of up and down) and allows debris to settle and then dry so it could be stopped up.

Took it to Chevy. Apparently it was an open seal where rain water is supposed to drain n the front of the car, but it filled up into the blower motor (as suggested here, thanks all!)

They "fixed it", and the car proceeded to leak again driving away from the dealer. The car went straight back to chevy, where they "fixed it" again, resulting in ANOTHER instance of the leak on the way home. Car went back to Chevy where everyone had already gone home for the day. The next day, they "fixed it" a third time. We will see if that's true when we get there today...

I suspect their first fix was a bulletin for an AC water problem but that wasn't your original problem....hopefully this is fixed permanently now.

Well, the car was picked up yesterday. It came home with no problem. Took the car to church in the evening, made a sharp turn, and out came more water onto the passenger side floor!

We had rain the night before - perhaps rain water is still finding its way in somewhere???

Back to the dealer for a 4th time on Monday...

Could be residual water from previous problem, however the drain should be letting the water out. Next time you drive your cobalt with the AC running -- when you park, pop the hood and look for water coming out of the drain -- if it isn't then tell them to look at the drain!
