My Car AC Smells Like Mildew or Foul Smell |

If your car smells like mildew or has foul smell when you turn on the air conditioning, then you could have fungus growth on the air conditioning (AC) component called the evaporator. Your car's AC system has an evaporator that is located underneath the dashboard. It is usually hidden behind the passenger's glove compartment. The job of the evaporator is to remove hot and humid air and turn it into dry cool air. The evaporator is enclosed in a dark box where moisture could still be present long after you've turned off the AC. Once the AC is turned off there won't be any circulated fresh air to dry off the evaporator. Overtime, the moisture that gets collected in the evaporator could be very problematic. Th problem occurs when a dark and damp closed box condition persists over time. This dark and moist environment is a perfect place for smelly bacteria to grow. When the bacteria started to grow, you could only expect mildew or foul smell to blow through every time you turn on your AC. What could make matter worse is if your evaporator system has a semi plugged drainage hose (which was designed to drained out the condensation created by the AC evaporator) water could leak into the interior of your car causing more trouble.

If your car smells like gas. All newer vehicles sold in the United States are equipped with electronic fuel injection systems. The electronic fuel injection system is much more efficient than its predecessor (carburetor). Even though the electronic fuel injection systems have pressurized gasoline line, no gasoline should escape under normal working conditions. For a normal operating system, gasoline should only be exposed or injected inside the engine combustion chambers. Once the gasoline has been injected, it gets burned off inside the engine systematically. Should there be any remaining gasoline after the combustion took place, the catalytic converter should burn the rest off. Then the exhaust gets pushed out through the tail pipe. The exhaust should not smell like gasoline. If you didn't spill any gasoline and your car smells like gas, then there could be a leak. The leak could exist any where from the back of the car (where the gasoline tank is stored) to the engine block.
If you smell gasoline, you should not drive your car or try to fix it yourself. Gasoline/fume leaks are fire hazardous and very dangerous. Get your car inspected immediately! Read More >>>

My Car Smells Like Burning Carpet |

If you're car smells like burning carpet or resin. A car's major brake components consist of the brake pedal, master cylinder, brake lines, rotors, calipers, and break pads. All of these components work together to slow down or stop the car. When you press down on the brake pedal, break fluid gets pushed through the brake system all the way down to the calipers, which squeeze brake pads. The calipers and pads work together just like fingers and gloves. These protected fingers grab onto the rotor to slow down or stop the car. Once you let go of the brake pedal, the calipers let go of the rotor. When brake calipers malfunction many things could happen. One of which they could get stuck in the grabbing or sticky position. When you drive your car with a sticky caliper, brake pads could become so hot and produce very strong smell. Some people say it smells like burning carpet, and some say it smells like burning resin. It's hard to describe the burning smell. But if the smell is strong and it is coming from one of the wheels, chances are you have a malfunction brake caliper. Get it checked ASAP as this could be very dangerous to drive. Read More >>>
