Don’t know how to troubleshoot the problem? Check out some tips here-Brought to you by PartsAvatar auto body parts.

Car’s Air conditioning system is something we take for granted, until we really get into a trouble. You won’t even know but your ignorance may cause you heavy expenses for replacement car air conditioning parts.

But don’t freak out. Here in this article, we will discuss what problem could occur with A/C and the best thing that you can do to deal with it!

One of the first things that you should check is the compressor engagement. If the compressor magnetic clutch is not engaging when the A/C is turned on, the problem may be a blown fuse. If the fuse is blown, replacing it could restore cooling temporarily.

But the main concept here is to know the reason behind the blowing off of fuse to prevent the same thing from happening again.

Is the air cooling?

There are several reasons an A/C system can lose its cooling ability.

All vehicles leak some refrigerants past seals in hoses. Any loss of refrigerant has adverse effect on car’s cooling performance. So, leaks can be devastating, you just have an open system when your car develops one. Early discovery of leaks could save you a lot of cash.

But if a leak has been affecting your cold air for a while, moisture will entire your car’s air conditioning system, thus damaging other vital components.

If your car’s air conditioner is clogged or not cleaned on regular basis, then the air flow will be restricted, this can lead to air conditioning unit simply not turning on.

You can clean the air conditioner by using a wet and dry vacuum to remove the grime or dust from the coils. You can also apply air conditioner coil cleaner on the coils to clean the rest of the grime off the condenser. This may not get the air conditioner to turn on but it will help increase the air flow when you do get it working.

Faulty compressor can also cause this issue. The compressor is costly to repair, so check if the switches are causing the problem first.

These switches can be easily replaced but replacing whole compressor can go out of budget. Compressor might have cracked or damaged belts, defective clutch, inactive pressure switches or idle valves. So, better take help of a professional.

Weird noise coming from A/C compressor

Noise from the compressor means it needs replacement. But noise can also be caused by cross contaminated refrigerants that have been operating in too high pressure, air in the system or the wrong compressor lubricant might also be the culprit.

Holes or broken parts can also be the source of the problem. As you might need replacement of compressor so be mentally prepared as it might not be that economical for you.

In the engine compartment, check the routing of the hoses, support brackets to pinpoint the noise. Let a trusted mechanic diagnose the original cause for you.

Air conditioning odour

It seems like you have an odour related problem in your hands. When your car has not been used for a while, especially during cold season, microorganisms like fungus and bacteria may germinate that will produce foul smell. This is not hygienic.

This time, dirty and old air cabin filter may be causing the nasty smell. Another culprit might be when water sits in the evaporator case the case’s drain is blocked then mold will accumulate. Drainage tubes should also be inspected.

Intermittent cooling

The A/C starts out cool then starts getting warm, what is happening? This can be caused by air and moisture in the system that allows ice to form and block the orifice tube.

Like other cooling problem, there might be various potential reasons behind this problem. The expansion valve distributes the proper amount of refrigerant to your evaporator and if the valve is blocked, the refrigerant can’t flow into the evaporator. With the valve clogged, the refrigerant will start to freeze.

Another possible culprit could be faulty compressor clutch. If the clutch is not engaging with your compressor then the compressor won’t be able to maintain a pressure resulting in dissipating hot air.

Leaks and A/C system are worst enemies. Presence of moisture or ignored damage could result in leaks. So, it is better to check for leaks when you notice any sign. Otherwise get ready to shed money on aftermath repairs.

Leaks in the A/C system

Age and moisture cause the air conditioning system to develop leaks. Rubber seals and hoses can also lose their elasticity over time and break down allowing Freon to escape and the moisture to enter A/C system.

As already mentioned above the leaky refrigerant is the death to car’s A/C system. You can check for leaks by adding special dye to the system, an electronic detector or plain soppy water to be sprayed on the hoses and watch for bubbles. Once you have noticed a leak, repairs should be made immediately.

But please keep in mind that if the evaporator or the condenser is leaking, repairs could be expensive.

Maintenance tips for air conditioning system

Above were the potential problems that you could face in near future related to air conditioning. Now, check out some useful tips to lower your expense of repairs and maintenance.

On regular basis, check for the cracks and damage to air conditioning compressor belt. Watch for any leak or damage in the air conditioning system.

Don’t avoid any problem like less cooling, moisture, smell etc. stated above. Do a vacuum test on air conditioning system and make sure the vents and coils are clean.

Empty out the refrigerant from the system. Use manufacturer recommended refrigerant to recharge your car’s A/C system.
