FAQs—Dodge A/C Compressor
How do you know if your Dodge A/C compressor is already worn?
Aside from oil and Freon leaks, one common sign of a worn A/C compressor is the inability of the air conditioner to properly coo the cabinl. Determine this by checking the compressor drive belt first. If it is loose, adjust the tension. But if it is already cracked and damaged, you'll need replacement. When you are sure that the belt is fine, you also need to check the magnetic clutch that is in the center of the pulley. This should rotate when the A/C is switched on, but will fail if the clutch does not engage. The latter problem can be due to faulty electrical connection and grounding, though. If both are okay, the fuses and relays need an eye as well. And if these parts are also working, the compressor may be the culprit. An expert air conditioning mechanic will best confirm your diagnosis.
What happens when the A/C compressor is contaminated with moisture, and how would I know of it?
When moisture makes it to the A/C compressor, because the receiver or dryer is already problematic, it will fail. Remember that A/C compressors are designed to handle gas and gas alone, so it will be damaged when it comes into contact with any liquid component. Not only that, corrosion will start eating the A/C system of your Dodge if the moisture mixes with the refrigerant. Poor cooling performance is one obvious result, although it is a vague indication, because the same problem also comes when the other parts of the air conditioner suffer from glitches. Another sign to watch is the moisture on glass.
How do moisture or liquid components reach the A/C compressor?
The common entry point of moisture is a broken valve. Oil would then leak, and the system won't be able to provide the performance that is asked of it. Significantly, replacement valve is what you need in order to solve the problem with the A/C compressor.
What are the ways to improve Dodge A/C compressor longevity?
Incorrect amount of oil can ruin your A/C compressor, whether it fell short or too much. The solution to this is to know the correct amount required. Compressors that come out in the market today are often pre-filled with oil. There are those who drain the oil from the compressor to be able to measure the amount of oil in it. Based on that, you'll know how much to add when the need comes. You can also ask the dealer about that, of course. Regular flushing also helps extend the life of your A/C compressor. This way, small but damaging particles that were able to mix with the oil are done away with.
How would you know that A/C compressor is working despite being inoperable?
Loss of power is the common cause of such a problem, thus faulty electrical connection and ineffective grounding can be the root of an inoperable A/C compressor. Defective capacitor can also be the reason, and the only way to determine the condition of the existing capacitor is to install a new one. If the latter works, the old one is damaged. The same thing needs to be done so as to know if it is the relay prevents compressor operation.
