I had my wipers motor replaced on the driver side. I did have to end up taking the car back to the shop because I noticed I had a small damage on the floor board of my car. The shop we did the installation to make sure that everything was done right but I'm still having a flooding problem has anybody dealt with the same thing my car is not overheating either I thought maybe thermostat. But my car runs fine other than one other issue I do know about
I'm confused as to what a thermostat or how the vehicle runs would have to do with an interior flooding issue, but it's possible that they messed up the seal there on the cowl plenum that goes over the windshield, allowing water into the cabin.
I took the car back to the shop and told them to fix their error apparently they put two hours into it and fixed it but after this rain my floor board on the driver side is drenched.
All right, so then I would take a look at the lower windshield seal that comes up from the cowl plenum, over top of the windshield - what does that look like?
Several things can be the cause. In the location of the wiper motor, the plastic cowl is supposed to deflect rain water. It could let it in somehow. Also underneath the cowl, there’s a bulk head and has drain holes to let water out when it drains from the windshield. Leaves and other debris will turn into compost and dirt over time and may clog the drain holes. This is quite common for people who park near or under trees. Even though I don’t park directly under a tree I still have to clean leaves and pine needles out of the cowl and around the hood occasionally.
The next thing that’ll cause a leak into the passenger compartment is the door seals. The ones on the Cobalt are not well designed. If they are deteriorated they may not squeeze tightly between the door and door frame. A flattened or worn seal may let rain or dew into the opening and let it drain into the floor area.
For things not related to rain or moisture coming from the outside, I can think of a few things. A clogged air conditioner evaporator housing drain. They also will clog with leaves, dirt, hair, and anything else that may get past the air filter. Usually this will occur only on the passenger side floor area and not get into the driver side. Also in this same area is the heater core. They can corrode and leak. Usually the leak will smell of coolant though and be more obvious. Also may have problems with the engine overheating at the same time due to losing coolant.
Not sure if anyone has figured it out yet but this really should not be rocket science to figure out. I usually start with spraying the car down with water. If it’s from the windshield area or doors it’s going to be pretty obvious. From the lower windshield or cowl, it’ll usually drip under the dash. You’ll need a really good pen light to see up inside. May need to take some of the plastic pieces off under the dash to see this area well. Most of the time I see a car come in for this, it’s a clogged cowl drain. Again you’ll need a pen light to see down into the area, after removing the cowl. In the cowl there are some foam pieces also. They may have broken apart and could have clogged the drains if they fell down into the bulk head area. Anyways, it seems like a lot of mechanics don’t know how to find or fix this stuff because I get cars coming to me that the dealerships can’t figure out half the times.
That was some detailed information thank you I'm going to try this and drop this Cobalt back at the shop is not my job to figure out what's wrong with it it's there it's the only thing I don't like is that they keep my car half the day and I provide care for the disabled and elderly right now is not the time to keep someone's car that long but they need to figure out what's going on with it.
I do have another question the second problem I have with my car I've got oil squirting out somewhere between the starter and motor, when driving the oil squirts onto my starter and then after a few stop lights it starts to lose power, I figured out that if I put it in neutral while I'm at the light it'll stay on and not die out I can't find out where the lakes coming from. Maybe you have some type of idea so I can check I'm a little bit mechanically inclined because my uncle owned his own shop but he passed I used to watch him while he did the cars, he tried to shooo me away but I just ended up on that other side of the car to watch lol.
Absolutely possible - usually you'll see staining on the headliner, if that's the case, but anything is possible.
I just had to clear out the front passenger drain tube on our Cruze because it had plugged, and then overflowed into the area above the roof console after a car wash. Not enjoyable.
