Categories: Floor Mat

As a car owner, we have to be vigilant about small discrepancies in the car to ensure major problems are avoided. We install different things within the vehicle to ensure the damages are limited. 

One of the most popular items that car owners use for protecting their car is a floor mat. We here at MudSmart offer premium all-weather floor mats that provide car owners maximum floor protection. 

However, if you have ever had your windshield fog up and found water under the carpet in the car, then you may have wondered how it got there. We have plenty of customers who ask us, “Why is my car carpet wet?” To them, we say there are plenty of reasons that can happen. 

Wet carpets are a common phenomenon for a car. So we listed five of the most common reasons why your car floor mats are wet. You will find all you need to know about damp car carpets in the following passages, so let’s start!

  • Blocked windshield cowl drain
  • Blocked air conditioning drain
  • Leaking heating system
  • Blocked sunroof drain
  • Windshield seal fault

Water leaks are simple problems you can quickly fix; however, it can create other significant complications that lead to thousands of dollars worth of damage if you ignore them for a long time. 

You have to make sure you fix the water damage before it becomes irreversible. Remember that water damage can even lead to health hazards, along with causing problems for your car. Here are some of the issues you will face if you ignore water leaks:

  • Bacteria and mold
  • Corrosion
  • Intermittent no starts
  • Premature component failure
  • Wiring faults
  • Control module failure
  • Carpet rot

Now that you know what the problems are with water leaks let’s go into more detailed discussions about the reasons for the water leaks. Let’s begin!

Blocked Windshield Cowl Drain

The purpose of a windshield cowl drain is to prevent large debris from passing to the firewall drain. The firewall drain or bulkhead drain is the one that sends out all the rainwater out of your car. 

The cowl drain usually catches all the debris, but some slip away, and those end up clogging the drain. That means water backs up and submerges body seams and body grommets, and you notice wet car mats. 

Fixing the cowl drain is very easy if there isn’t any wire corrosion. You can lift your hood and have complete access to the drain. Use a flashlight to look for signs of standing water behind the cowl. Then clear out the water through the firewall drain, and you are done.

Blocked Air Conditioning Drain

Air conditioners cause condensation, and that’s why most modern cars come with air conditioning drains to help with drainage. The evaporator for the air conditioning handles all the moisture problems. It is connected to the firewall drains through which all the moisture gets released. 

When the rubber evaporator on the side of the firewall blocks up with debris and causes the evaporator moisture to build up and overflow inside the car, there will be condensation when you have the A/C on drip under your vehicle. 

If the vehicle is parked, you will be able to see the pool under the car, and if it’s clear, then there is no problem. However, if the puddle isn’t clear, you may have a different leak on the a/c drain. If there isn’t any liquid drip, then it might mean there is a clog, so make sure you check out the a/c drain.

Leaking Heating System

As time goes by, the coolant for the heating system degrades into a harmful liquid. It can turn acidic, and it will attack metal, rubber, and plastic components, breaking them down. Your car’s heater core is susceptible to damage, and it can be easily damaged by frost, corrosion, and plain-old wear and tear. 

When that happens, the coolant delivery system behind the dashboard can leak, resulting in wet car floor mats. There are a few ways you can notice if you have a coolant leak or not:

  • Chesty cough
  • Fogged windows
  • Low coolant level
  • Sweet smell inside the car
  • Damp carpets
  • Mold and stale smell

Coolants are harmful to you as well, so make sure you check them out whenever you see any of those above symptoms. It would be best if you started stripping out your car’s floor mat. 

If there’s a leak, you will see pink, greenish, or yellow liquid in color, and it will irritate your skin. Remember coolant leak is a big problem, so you have to take the car out to the garage to have it fixed.

Blocked Sunroof Drain

If your car has a sunroof, then you might have had a blocked sunroof drain problem. When the sunroof drain is blocked, you can find wet car floor mats. Three significant issues with your sunroof can cause wet car floor mats

The sunroof drain seal can be damaged with age like any other drainage system. However, you can easily change the assembly and have the issue fixed. 

If you want to check the sunroof drainage system, then all you need to do is pour a jug of water on the four corners of the sunroof and see if the water comes out quickly through the other end. If you see a blockage, then poke it through have the debris cleared up.

Windshield Seal Fault

Usually, the windshield of your car is bonded in with unique sealers. The seal can break down over the years or if your vehicle is exposed to extreme temperatures. Under normal circumstances, factory windshield setups don’t cause many problems.

However, if you see a wet carpet in your car and you suspect windshield problems, then you have to check for it. When inspecting for the seal fault, you have to make sure you remove the car floor mat. 

Once the mat is removed, run a hose at the windshield pillar and leave it running until the leaks pop up. Ask someone to hold the hose while you get into the car and check for the leaks. 

Use a flashlight and work your way up from the bottom to isolate the leak. Windshield leaks can be dangerous as it can lead into the kick panel area, so ensure you are thorough with your check-ups.
