Why is my car air conditioner not blowing cold air?

You don’t have to wait for the warmth of summer to be here in full force before looking for auto AC service. Even though we have looked forward to warmer temperatures, most people still like to stay cool and relaxed in their car even if it’s just for a short commute to work or to pick up groceries.  It’s especially important if you’re planning a summer road trip.  

Don’t find yourself out on the road wondering, “Why is my car air conditioner not blowing cold air?”  There are various reasons that could cause this issue:

• The coolant has lost its efficiency.  Fresh coolant added to the radiator may be all that is needed for the AC to work again.   
• The AC’s compressor is not creating a high enough pressure in the system for the refrigerant to cool correctly.
• A block in the system is allowing the high-pressure refrigerant to slowly decompress through the block. 
• Constantly exposed to stress from the health of the engine, road debris, dirt, vibrations, quick stops, and even run-ins with curbs, small cracks can be created in the AC unit through which the refrigerant is escaping.  
• The cooling fans could be burned out, mounted incorrectly, a chipped blade, or a simple blown fuse or burnt-out relay.
• An issue in the electrical system is giving out faulty signals caused by a broken wire or bad module, bad sensors tripping off your system, or causing the system to shut off inadvertently.  

With the use of computerized parts in today’s vehicles, the AC system is more complex than ever.  At least once a year, schedule an auto AC service with an auto mechanic who is certified to handle refrigerants. You will reap the benefits of not only a more relaxed drive in summer’s warm temperatures, but increased gas mileage, and a more environmentally-friendly vehicle.

What Does a Full Service Include on a Diesel Engine?

After several considerations, you may have decided to purchase a diesel car or truck.  But your question now is what does a full service include on a diesel engine?  How should you take care of it?  It is important that you find a trustworthy diesel auto mechanic that is qualified to answer your questions and perform the needed maintenance services.

In several respects, a diesel engine is not as complex as a gasoline-powered engine, and will provide you with greater reliability.  Diesel engines use compression in the combustion chamber to ignite the fuel instead of a spark like in a gas engine.  That means that diesel engines don’t require ignition tune-ups, plus they tend to run longer without major repairs than gas engines.  

That said, today’s newer diesel engines are more complex than in years past.  Due to higher emissions standards, increased horsepower, torque, and their advanced technology, the maintenance required for diesels has also increased.  Usually, a full service on your diesel car or truck includes:

• Changing the oil and filter—use the correct grade for your diesel engine
• Changing the air filter—Catches sand and other debris
• Changing the fuel filter—keeps the fuel clean so there is no water or contaminants in it
• Bleeding the fuel system—flushes out contaminated fuel
• Draining the water separators—some drain automatically
• Refill injection system—reduces nitrogen oxide emissions.  

The maintenance schedule for your diesel vehicle can be found in your owner’s manual.  Also, be sure to ask an ASE certified diesel auto mechanic to help you understand the schedule for your specific vehicle and then help you prioritize and budget for these services.
