Nissan Xterra Ac Compressor

Finding the Culprits of a Faulty Nissan Xterra AC Compressor

The Nissan Xterra AC compressor allows your vehicle cabin to be cooled and comfortable to ride in. As the car ages, its parts also do and sooner or later, the components will give up on you. So before that happens, you might as well diagnose the AC compressor to find out if it's already about time to have it repaired or replaced. Here are some troubleshooting tips that you can use at home.

Weird noises

When the AC compressor is about to get damaged, it usually makes odd noises. Listen to the unusual sounds and try to locate where they come from. The compressor of some air conditioners make use of an electrically actuated clutch mechanism that can create a harsh grinding noise when it's about to give up. It could also mean that the internal bearings have lost their lubricant, which can make awful sounds. Also, if the timing belt is loose, it will make squealing noises. Have the AC compressor replaced right away.

Used-up fuse

At the dashboard panel, inspect the fuse; you can also locate larger ones underneath the hood. Check if there are any blown fuses that might need to be replaced. You can also locate a secondary fuse panel in the engine compartment. Since they are larger, they can handle more current. If there are any blown fuses, make sure to replace them with the right amperage.

Low refrigerant level

The compressor clutch engagement should also be checked to find out if the AC compressor is busted. Switch on the air conditioner and set it to its coldest setting. Start your car with the engine on idle. Lift the hood and study the clutch, which is located in front of the compressor; check if it is turning. If it is, then your AC compressor is still in good condition. Otherwise, it means that the AC system is low on refrigerant and would not be able to work as it should. It will also start to make a ticking sound. You may need to recharge the system using an air conditioner recharge kit.

  • Taking Care of the Nissan Xterra AC Compressor

    The AC compressor allows you and your passengers to be comfortable at all times especially when you take really long trips. There are some old cars that have no functioning air conditioners; imagine how they feel whenever they drive under the summer's heat! You wouldn't want that to happen to you. It's quite inevitable even for the Nissan Xterra AC compressor to fail. Before that happens, you must take note of the signs and symptoms so that you can immediately save your compressor.

    Clean the dirt buildup.

    Whether you like it or not, dust or debris will enter the air conditioner. Be sure to clean it up before it even gets to the AC compressor to avoid any complications in the system.

    Schedule a regular cleanup.

    It's unavoidable for the AC compressor to overheat especially when it's contaminated. So, to avoid any premature heating, regularly clean the air filter. Take note that the AC compressor sucks in dirt and other contaminants and goes right into the air filter. If this gets clogged up, dust won't be able to enter through it, which will make the compressor compensate by working even harder. You can simply use a soft-bristled brush and a pressurized water hose to sanitize the air filter. Keep in mind that it should be completely dry before you install it back in.

    Maintain gas pressure.

    If you switch on the air conditioner once a week for ten minuteas straight, you'll be able to maintain the right gas pressure. It will keep the hoses from hardening and AC compressor seal to fail. You can simply turn on the air conditioner to its coolest setting and highest fan speed. To clean the accumulated moisture, turn on the defrost mode for five to ten minutes to prevent any mold or bad odor to circulate in the system.

    Close the windows.

    Since it's really inevitable for any dust or dirt to enter the AC compressor, the best you can do is to at least try to prevent it or minimize the contaminants that enter. When your air conditioner is on, make sure to close all the windows. Also, when you're driving on a dusty trail, the glass windows should also be shut because dirt would definitely enter the system and can harm the AC compressor.
