2005 jeep liberty speedometer not working: The malfunction of the 4WD system of the Jeep Free Optical is that the 4WD system is often not selected during driving, and the instrument panel prompts that the 4WD system is unavailable and needs to be repaired. Seeing this prompt, we experienced and judged that this kind of fault was basically caused by the motor fault of the transfer case. The transfer case plays a key role in the process of power transmission and transformation. The transmission distributes power to the transfer case, which then transfers power to the front and rear wheels for power distribution. The failure is due to the failure of the motor of the transfer case, which leads to the unreasonable distribution of power.
When the transfer case control module is disassembled, there is a power transmission unit inside, which is used to control the fork to complete the switch between the 4WD and the front drive. The power is completed by this motor. This motor smells of a strong smell of burning. The appearance of the motor is very obvious. The appearance of the motor has been burnt black. The sealing effect of this gasket is also very bad. The oil leakage is very serious. It is all oil. The motor must also be filled with oil. Next, we started to dismantle the motor. It was very troublesome to dismantle the motor. If we didn't find the right person, it would be troublesome to repair it. The motor was disassembled and opened, and all the leakage was oil! The carbon brushes are all worn out, they are all slag, which blocks up the inside, causing the motor to fail to work normally. The signal panel is also full of oil sludge and garbage, which need to be cleaned up. Then replace the broken motor with a new one. The maintenance is almost over here.
In fact, many gearbox failures look very serious, but many of them are caused by a small internal part failure. As long as the fault can be accurately identified, maintenance costs are really small. So, it's still a cliche. It can be repaired and solved. It's really unnecessary to replace the assembly.
