I think it's really important to know a bit about the internals of a car, so that when you are getting your car serviced you can talk intelligently with the auto technician. As well, there are many easy DIY jobs you can do on your car to save your some money which can make all the difference when you are young and starting out. This site is where I am recording everything I am teaching my kids about auto servicing, and because I think it will be useful to many other families as well. I hope you find it useful for your family.
Your car's air conditioner helps cool or warm you whenever you're driving around. Therefore, a faulty air conditioner can culminate in some serious level of discomfort especially during those sweltering summer days. You're supposed to receive optimal service from your car's air conditioners year through without dealing with the hassle and stress associated with frequent letdowns. The following points will help you know where to start from the next time you're facing problems with your car's air conditioner so that you can solve them quickly:
Low refrigerant level
When troubleshooting an air conditioning problem, it's always advisable to start inspecting the compressor unit since it is most likely that low refrigerant level is responsible for the failure or poor functioning of the system. Typically, compressor failures result from the loss of lubrication, which may be subsequently caused by low refrigerant level in the air conditioners.
In the event that the compressor unit of your car's air conditioning fails to turn on when you engage the magnetic clutch, then, you most probably need to increase the refrigerant level! You will have to regas the system as soon as possible.
Leaks can result in devastating, damaging effects on the air conditioner in your car. When your car's air conditioning begins to leak, moisture will probably enter the system and may damage some vital and costly components such as the expansion valve.
The expansion valve, for example, ensures that a sufficient amount of refrigerant is supplied to your evaporator. If the valve gets clogged, the refrigerant won't find its way into the evaporator. Consequently, the refrigerant will in turn begin to freeze the valve if there is moisture.
Identifying and sealing leaks found around various components such as the evaporator unit, condenser unit, expansion valves, and pressure switches will help keep your car's air conditioners in the best working conditioning.
Apart from the refrigerant side, your car's air conditioning problems may also arise from the electrical side, which supplies the power needed to keep the refrigeration process working; if the fuse connected to the system is blown, then power supply to important components such as the compressor unit will be cut, disengaging its components in the process.
If you check and realise that the fuse is blown, changing it may bring back cooling or warming temporarily. However, you may need an expert to investigate, identify, and correct the underlying reason why the fuse blew in the first instance to prevent the same problem from occurring repeatedly.
