Teana seat massage fuse is under the glove box of the co-pilot seat. The fuse boxes of general models are beside the engine and in front of the steering wheel. When you open the cover of the machine, you can see it. The fuse box of various models is located in the lower left corner of the steering wheel. Others are located on the co-pilot's side, glove box, trunk and engine compartment. The use of car fuses is similar to that of household fuses. When the current of the circuit is abnormal and exceeds its rated current, it fuses and plays the role of circuit protection barrier.

principle of operation

When current passes through a conductor, the conductor will generate heat because of its certain resistance. After the material and shape of the fuse are determined, its resistance should be determined. When current flows through it, it will generate heat, and its heating value will increase with time.

The size of current and resistance determines the speed of heating, and the structure and installation of fuse determine the speed of heat consumption. If the heating speed is less than the cooling speed, the fuse will not blow.
