As springtime approaches and the temperatures start to rise, drivers will be turning their air conditioners on for the first time in months. Sometimes we can come across unexpected noises or issues when we use a system again after a long break. Here are three common problems that can cause your car's air conditioner to rattle.
- Failing AC Compressor
Before the refrigerant that causes your AC system to blow cool air can be pumped into the condenser, it needs to undergo intense pressure. This is the job of the AC compressor. The AC compressor can become worn over time, requiring replacement.
- Worn Serpentine Belt
The serpentine belt is connected to many of your car's accessories, like the air conditioning, alternator, power steering pump, air pump, and more. This belt can become worn over time leading to poor tension and noises like rattling or squeaking.
Find the serpentine belt and look for any signs of wear.
- Bad Idler Pulley
Idler pulleys are used to guide, connect, and create tension for the various engine drive belts that run with your vehicle's engine. So, your serpentine belt that connects engine power to the air conditioner may be fine, but the idler pulley that runs with it may need to be replaced. High mileage vehicles will likely need a replacement pulley, but this is a fairly inexpensive fix.
Don't put up with faulty parts or annoying noises in your car, know what to look for and how to fix it. Understanding your vehicle and keeping up with its needs will help it last longer and make for more enjoyable drives.
