What causes my carpet in my Honda Ridgeline to be wet all the time
It can be quite a few things Lisa, but the most likely things are the windscreen rubber has perished, and letting in water (this would be more common on older cars). If your car is more modern, it will probably have a bonded screen. If so, has it recently been replaced? If so, it might be worth approaching the screen fitter to get the screen re-sealed under guarantee.
Run a hose over the front window for a while, while checking below the dashboard to see if you can see where the water is coming in.
There is also a possibility the drain holes in the windscreen scuttle may have become blocked. The scuttle is the bit between the bonnet and the windscreen. It usually has a grill cut into it.
If this is blocked, try to access the drain tube with a long rod to try and clear it out. A common occurrence if your car is regularly parked under trees / bushes, or in dusty areas. Sometimes, you may be able to see a puddle of water collected below the scuttle grill.
The worst result could be rusty floor pans. Most common on older cars. Very rare on newer cars. If you find the carpets become wet only after you have driven in wet conditions, then it is certain to be caused by rust holes in the floor. If you are unlucky enough to have this problem, it might be a good time to get rid of the car.
I can be repaired, but can be very very expensive.
For some very old cars (1960s to 1970s), you can find floor repair panels, but these are less common for newer cars.
You could also have a leaking sunroof. A good competent mechanic should be able to offer a few options to fix that. Start with a hose over the car, with kitchen roll over the carpet to help show up where the water is coming in.
Good luck.
