Why does the car consume significantly more fuel when the air conditioning is on?

When the car consumes significantly more fuel with the air conditioning on, it is usually due to an aging air conditioning system or engine, which increases fuel consumption, or it may be related to driving habits. Relevant information is as follows: 1. When the interior temperature is high: During summer days, room temperatures often exceed 30 degrees Celsius. For cars parked outdoors under the sun, the sealed cabin can become extremely hot. Trying to lower the temperature immediately by blasting the air conditioning is not only ineffective—since the temperature cannot drop rapidly—but also leads to a significant increase in fuel consumption due to the air conditioning working at full capacity. 2. Solution: Instead of relying entirely on the air conditioning, it is better to first open the doors and windows to allow the hot air inside the car to dissipate quickly. Once the interior temperature approaches the ambient temperature, you can then turn on the air conditioning in recirculation mode to cool down the cabin.

What Causes Water Leakage in the Malibu Trunk?

Malibu trunk water leakage can be attributed to the following reasons: Worn or Aged Sealing Strips: The trunk sealing strips may be worn out or aged, or the trunk itself may be deformed. Clogged Drainage Pipes: Leakage can occur due to clogged drainage pipes. Since the trunk is not completely sealed, some dirt or sand may enter the drainage pipes during rain or car washing. The drainage holes are designed to be small and can easily get blocked by dust or sand. Maintaining Trunk Cleanliness: To prevent trunk leakage in daily use, it is essential to keep the trunk clean, ensure the drainage routes are clear and tidy, and maintain the sealing strips' integrity. These measures can significantly reduce the chances of trunk water leakage. Daily Maintenance Tips for the Trunk: During regular car washing, clean the sunroof and rear water drainage channels thoroughly and unclog the drainage holes.
