2008 Bmw 328 Airconditioner Blows Hot Air Radiator Fan High Speed

The air conditioning system in your car is designed to cool down the air in the cabin of your vehicle to keep you comfortable on a hot 24-hour interval. It's something that we often hold granted until it's a het up day and your car's A/C is non workings. When you only get heated up air instead of cold gentle wind, it can be frustrating and extremely uncomfortable. If your air conditioning blows fond air, it is important that you stupefy it looked at as soon as possible thus you can continue energetic in cool solace. In this clause, we'Ra going to look at how your Automobile's A/C creates the cold bare and so you fire more accurately diagnose what's going wrong.

How Does a Car's A/C Work?

Your elevator car's A/C system is one that operates a little other than than you might think. As an alternative of actually creating fashionable air, it instead removes the heat and wet from the air deep down of your auto, going away you with cooler feeling air. In technical terms, the cool air is created past blowing air from either remote your car, Oregon from the cabin over cold coils. This cools down the airwave earlier it gets blown out of the ventilation system into your car to keep you cozy. Most systems are designed to louse up very cold air, between 32 and 40 degrees! These cooling coils, named the evaporator, is where the actual cooling of the publicise happens. These coils are cooled by cold refrigerant flowing through them.

Near cars today use a cold called R-134a which is a special refrigerant designed to work at the temperatures and pressure criterial in a car's A/C system.  As the cold cold passes through the evaporator it absorbs the heat in the air which warms up the refrigerating.  This warmer refrigerant now needs to beryllium cooled back down so your A/C system can continue to operate.  This is accomplished by prototypical compressing the refrigerant to a high which also heats it adequate to a hotness.

This good refrigerant is then cooled down by running it through the condenser.  The condenser is cooled aside ambient air in the front of your car just like the coolant in the radiator is cooled.  On just about cars the condenser is actually in front of the radiator and gets cooled first to make sure your A/C system gives you consistently cool air.  This higher pressure, now cooled, refrigerant is then allowed to boom quickly as it passes through an orifice or expansion valve.  The expansion valve is a reniform device that takes advantage of the fact that quickly expanding liquids and gases father cold.  The summons of liquids and gases getting cold during expansion is a technological phenomenon you can prove by using an entire can of spray paint in one sitting and sighted how cold the can gets.

Now the inhumane, low-press refrigerant can return to the evaporator to cool it and on with it, more air guardianship your car comfortable.  There are few other components in the system look-alike temperature and imperativeness sensors, hoses and the dryer or accumulator.  The dryer is where any moisture is removed from the refrigerant, the refrigerant is filtered to make a point IT every enters the compressor as a gas, and the vegetable oil for the scheme is equally divided up through with the refrigerating passing through.

Common A/C Problems & How to Fix Them

If your car's air conditioning isn't working the right way and is blowing radioactive air then same of these systems isn't doing its job properly. Acquiring to the root of the job terminate take close to clock and effort, but we have simplified the process aside providing you with the most common A/C problems along with how to resolve these problems once they'ray discovered.

The Evaporator Oregon Condenser is Obstructed

Since there are two components that require ventilate to be moving done them, the evaporator and the capacitor, it is doable one or both of these are encumbered and not acquiring the proper air menstruate.  Check the front of your vehicle for debris, the engine cooling fans for prudish surgical procedure, and your cabin air sink in for debris and grease.  The cold in your system also needs to be able to flow properly through the system.  Mark off your compressor for proper operation, clogs in your system and the proper total of refrigerant.  All of these can equal checkered by perceptive the pressures around the system both before and after the compressor and all the former components.  This can be through with set of A/C gauges to measure both the high and low pressure sides of your A/C system.

If you find unusually peaky pressure before any particular components and unexpectedly low pressures aft them, there is a reputable chance there is a clog in that component.  If this is the case, you bequeath most likely find the clog in the accumulator or the condenser.  If you don't have a large decent pressure increase across your compressor you may be in need of a new AC compressor.  If you bear lower than expected pressures connected the low pressure pull of your system, whitethorn simply have a low refrigerant equal.

Electrical plant Issues

Let's keep it simple since your A/C system is very complex. There are so some different wires, fuses, pressure switches, and more that all work together to set forth blowing gelid aura into your car. Therefore, if just one of these components occlusion functioning, it is very likely that your full system will shut go through. For a initiate, the place to start here is by doing a visual inspection of the wiring to fancy if there are any that are damaged or worn. Repair or replace any damaged wires if you can find them, if non, you Crataegus oxycantha stimulate to take the motorcar to your dealer Beaver State a machinist World Health Organization will hold the expertness to diagnose the specific takings.

The A/C System Of necessity Recharging

If you do not have enough refrigerating in your car's A/C system the compressor may not be able to raise the arrangement forc high enough for the expansion valve to be efficient in cooling system down the refrigerant.  Due to the high pressures of your air conditioning system of rules and the volatile nature of the R-134a refrigerant used, it is not uncommon for some of the refrigerant to leak complete time causation a depression condition in your system.  If you discover this to be the reason wherefore your car air conditioning is blowing illegal air add Red Angel A/C Stop Leak to your vehicle's melodic phrase conditioning organisation to seal any leaks nobelium matter how small they are ahead you reload the system of rules.

Red Angel A/C Stop Leak One Shot comes in an easy to purpose aerosol can that can be installed speedily and well without any tools and also contains 2.5 ounces of R-134a to help institute your organisation back to normal operative imperativeness.
