In most cases, when I think or even guess, I pay the price. Although my guess is 24 years of practical experience, it is wrong almost 50% of the time. This means, I just increased my diagnosis time, liquidation and replacement of parts that was not necessary.
This brings me to the real problems troubleshooting car. Getting a good auto repair manual and perform all the step-by-step diagnosis that the troubleshooting manualprovides. If you feel the problem, do the extra step and check the components found.
For example, say you are diagnosing and overheating. Your educated guess says that you must replace the thermostat. Why not go one step further and actually test the thermostat throwing boiling water and see when they open? If the thermostat does not open, while you soak in boiling water to know that this is not yourOverheating problem. For the same example, you can hear the fan motor to replace. Once again we take the extra step and test the fan operation. Applying 12V Power to the side of the fan motor and grounding the negative side can test the fan operation. If the fan motor kicking and running, you know that this is not the problem with the heating.Car window repair
The next step would be to consider what is on the fan motor. In most casesis a temperature switch and a fan relay that the runway will be complete with electric motor. Both the temperature switch and relay can be tested.
As you can see the problems in the car from the previous examples, if you are troubleshooting, problem may be more a response to what the cause. Just guessing, and threw the vehicle can cost more than if you took the car in a repair shop and had someone else do the work.Car window repair
The reason why we workon our own cars and build-it-yourself auto repair do is to save money, downtime on the vehicle and learn about troubleshooting in the process of self. With the above example again, say that your vehicle overheating problem of a bad connection to the temperature switch was activated, the fan motor, I've seen many times. If you replaced the fan motor and the thermostat, you have just over $ 300 in parts and spent a whole dayWorking on things that did not need replacing. Your problem may be overheating was free, no pieces
