The reasons and solutions for why the fuel tank cap cannot be opened are as follows: 1. Fuel tank cap: The fuel tank cap is stuck or rusty. Gently pry or tap to open it. 2. Motor failure: Most vehicle fuel tank caps rely on a motor to lock, so the fuel tank cap may not open due to motor failure. Some vehicles are equipped with an emergency fuel tank cap release. Pull the emergency release handle with a little force while pressing the fuel tank cap to open it. 3. Loss of elasticity in the fuel cap spring: Install a small spring at the protruding rubber pad of the fuel tank to increase the elasticity between the fuel tank cap and the locking device.

Where is the Tiguan's air conditioning fuse located?

Inside the vehicle's fuse box (located behind the dashboard storage compartment cover). The automotive air conditioning system serves the following functions: 1. Temperature regulation: This is the primary function of car air conditioning. In summer, the cooling system produces cold air to lower the cabin temperature; in winter, except for large commercial vehicles that use independent combustion heaters, most vehicles utilize waste heat for warming. 2. Humidity regulation: Humidity significantly affects passenger comfort. Cabin humidity should generally be maintained between 30%-70%. Standard car AC systems don't have humidity control functionality - only through ventilation systems or advanced luxury vehicle integrated climate control systems. 3. Airflow regulation: Airflow speed and direction greatly impact comfort. For direct airflow, when temperature is appropriate, speed should be limited to a certain range, which can be adjusted based on passengers' living environment, age, health condition, and temperature preferences. 4.
