Leak into wheel well

I found water leaking into the wheel well a few days ago. So I replaced the rear door seal. It didn't do any good, and it still kept leaking water. Do you have any ideas or suggestions? Thank you.
Experienced mechanics share their insights in answering this question :
A few different items can cause a leak into the vehicle. The door seal was a great place to start in this case. Other areas to consider for a leak like this include the window trim or body seam.

If you need assistance with getting this fixed, enlist a qualified technician who will be able to diagnose the source of the water leak and perform any repairs that are required.

If you find a fluorescent green, blue, orange, yellow, or pink puddle underneath the engine area of your car, chances are it`s radiator coolant. Also known as antifreeze, coolant contains ethylene glycol, which smells slightly sweet, like maple sugar or candy.
One simple test to look for the source of a leak is to create positive pressure inside the vehicle. Turn the air conditioner on to the fresh air setting, turn the blower on high, and close all the doors. By wetting your hand and feeling around the seals, you`ll be able to see if any air is escaping.
Look for signs of coolant leakage—a light-colored residue or stain—around the radiator cap, on hoses throughout the engine compartment (check the ends where they are clamped to other components) and on the radiator itself. If it looks like a hose is leaking near a clamp, try tightening the clamp with a screwdriver.
The A/C builds condensation in the vent system that is under your dash. The system has a drain hole, but sometimes the hole becomes clogged with debris, and sometimes bugs like to go in there and build their nest. This is common in the spring. The solution is simple, just unclog the hole.
One of the biggest culprits is damaged weatherstripping or a bad seal around the windshield. If you have a sunroof, it`s not uncommon for that seal to wear down because it`s in direct sunlight a majority of the time. Also, a cracked windshield can lead to leaks depending on the type of crack that you have.
A few drops of water leaking from underneath your car is most often a normal occurrence. When it`s uncomfortable outside and you have the A/C on full blast to keep you from melting into a puddle on the sidewalk, your cooling system is working harder than normal.
In the vast majority of cases, your car leaking water is usually condensation from the air conditioning system, or from the exhaust. If you see water dripping from under your car when ac is on around the rear of the engine compartment, it`s likely going to be just AC condensation.
Usually, leaking water is simply condensation from the aircon unit – surprisingly common during summer – or the exhaust, which is more common in winter. Another typical cause is your windscreen washers, but again this is unlikely to be a major issue and you can probably just ignore it.

The heater core is heated by the engine coolant. Air is then blown over the heater core, by the blower motor when the heater is on, to heat the passenger compartment. If this core develops a leak, it will usually leak into the passenger compartment floorboard.

Baking soda is a cheap solution to excess moisture. Open up a few boxes of baking soda and let them sit open in the vehicle with all the doors and windows closed. Do not pour baking soda onto vehicle surfaces. Baking soda, while still in the open box, will help absorb excess moisture.
One of the most common reasons people discover leaking windows during rain is damaged or missing sealant or caulk. Caulking is one of the simplest and most overlooked causes of window leaks. Any damaged caulk around the exterior of the window should be cleared out and replaced with a new bead of silicone caulk.
Pouring hot water over a car`s windshield during low temperatures can damage it, causing it to crack or shatter from the sudden temperature change.
A few drops of water may not seem like a big deal if you can easily wipe them up, but a leak around your windshield is nothing to ignore. A windshield leak left untreated can lead to extensive water damage to your car. It may even affect the resale value of your car.
The short answer is yes, but it is not recommended. Ignoring a blown head gasket will likely lead to more damage to your engine as well as your wallet. Gaskets are some of the most important and necessary parts of any engine which function to seal off compartments.
There are some very common causes for that water under your car, including: air conditioning, exhaust, and the windshield washer fluid reservoir. If the puddle under your vehicle is colorless and odorless, there is a good possibility it is just water dripping from your vehicle`s air conditioning system.
It could be a leaking hose or a radiator hole. Solution: Check to see if any coolant is leaking from your hoses. If you find coolant flowing out of the hose(s), replace them. It`s a simple fix if you find coolant leaking from your thermostat.
Rain Can Cause Mildew Growth In Vehicles

In extreme cases, a high level of enclosed dampness can cause health problems like asthma. If you notice moisture in your vehicle after it rains, make sure you clean it immediately to avoid harmful effects.

Leaving your windows slightly open allows air to circulate through the car – particularly as the hot air inside rises. However, if your car is parked outdoors, we don`t advise leaving more than a couple of centimetres gap between the top of the window and the door frame.
Blow the switch out with compressed air.

Use a can of compressed air to push as much moisture out of the switch as possible. It will dry the switch quickly, which means water will not sit in the contacts, causing corrosion.

Companies in the plumbing industry find FloodSax® water absorbent pad to be the best, as it is 25% larger than other similar products, therefore absorbing and RETAINING much more liquid. Each Floodsax® water absorbent pad can hold about 5.8 gallons of liquid. As an innovative water absorbing bag, it weighs only 1 lb.
Excess water and moisture gets absorbed into wooden window sills and frames which can lead to rotting and discoloration. Your flooring and furniture will also soak up rain water which can cause problems such as warping and deterioration. You must remember to close your windows once it starts raining.
Water leaks between the sill pan and the window sill are more likely to occur near the bottom where the sill slopes. The sill of every window should slope away from the window so that water can drain to the exterior of the house. The window may need to be reinstalled if either of these is incorrect or missing.

I hear an abnormal noise from front driver’s side wheel. It sounds like a wheel bearing but not sure.
ANSWER : A wheel bearing noise can be different between vehicles as some designs may vary a little. The most common is a roaring noise that may change when going around turns. It may be louder going in one direction or the other or just make a loud noise all of the time. The wheel hub presses into the wheel bearing. The hub is where the studs are for the wheel to be bolted onto the steering knuckle and the bearing provides the support for the wheel and weight of the vehicle. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your wheel bearing noise to offer a more personal diagnosis.

Brake line leak front right wheel well.
ANSWER : When the metal brake lines have leaks you need to first look to see the reason for the leak. Was the line damaged by something hitting it, rubbing through it or is the brake lines rusted to the point of springing leaks? In any of the cases you will need to replace the brake line with a new one. In most cases the line will need to be made from bulk brake lines since the factory will only have new metal lines available for a few years after production. The rubber lines are available from dealer and aftermarket in most cases.

I have a leak in the coolant system that I have narrowed to I believe is the water inlet tube off of the lower radiator hose.
ANSWER : First off, I would say it would be best to pressure test the cooling system to verify where the coolant is coming from. With the complexity of repairs to the cooling system on this vehicle, it may be worth the time spent to pressure test the system before tackling the replacement. Now then, as far as replacing the o-ring seal on the water pump inlet tube, it should really only require the removal of the bypass hose, lower radiator hose, and the two (or three, depending on manufacturing changes) mounting bolts that hold the inlet tube to the block. I personally would go ahead and replace the tube while I was there, instead of just the o-ring. Granted, this doesn’t mention what it will take to get down to the inlet pipe, but this is all it should take once you have access to it. If this is something that you feel you could use a hand with, consult with a certified mechanic, like those available at YourMechanic.com.
