Methods for inspecting the quality of a used car: 1. Check the exterior wear and tear. Choose a well-lit area and observe the car at a 45-degree angle to spot any scratches or hidden dents; 2. Inspect the body frame for damage. If the car has been in a major accident, the frame will show varying degrees of dents or misalignment; 3. Find out why repainting or bodywork was done—whether it was due to minor scratches or a severe collision; 4. Check the wiring harness in the engine compartment for corrosion or aging, and inspect the engine block and mechanical parts for mold spots; 5. Look for leaks in fluids such as engine oil, brake fluid, and coolant.

What to Do When the Charging Cable Interface of New Energy Vehicles Overheats?

Improve the materials of the charging interface for new energy vehicles. Relevant details are as follows: 1. Different materials: Generally, when charging a new energy vehicle, the interface chips of the vehicle and the charging pile are made of different materials. Under high voltage and large current conditions, overheating is highly likely, which can cause deformation of the charging interface. This primarily applies to the first generation of new energy vehicles. 2. Special materials: Modern new energy vehicles use new high-temperature-resistant special materials for their charging interfaces. Moreover, these materials also have excellent heat dissipation properties, significantly reducing the heat generated at the charging interface.

Why doesn't the Jetta have a low-speed fan?

The Jetta's low-speed fan not working is mainly due to reasons such as the temperature control switch and thermostat. Temperature Control Switch: The temperature control switch, also known as the thermal switch, if the live wire and the wires for gears 1 and 2 are connected and functioning normally, proceed to the next step. If any gear does not work, the temperature control switch is faulty and needs to be replaced with a new one first. Thermostat: Open the cap of the cooling system expansion tank to release the pressure in the cooling system. When the cap can be opened, test whether the temperatures of the upper and lower water pipes are the same. If the two hoses from the engine to the radiator are at roughly the same temperature, the thermostat is functioning properly.
