Pontiac Firebird Ac Compressor
How Your Pontiac Firebird AC Compressor Can Go Wrong
Being the core part of the air-conditioning system, the AC compressor enables you to keep your cool during the hot days. However, keeping your cool is impossible if the part that supposedly saves you from the heat is the one giving you headaches. Save yourself from the heat and find out what causes your Pontiac Firebird AC compressor to fail. Listed below are some of the common problems experienced with the compressor.
Leaks in the AC system are quite common for car owners, who often blame the entire air-conditioning system for it. Actually, leaks are usually caused by a faulty compressor. Your Pontiac Firebird AC compressor assembly is made up of a lot of moving parts that need a considerable amount of lubrication. The leaks would be the lubricants applied on these parts escaping.
It is fairly easy to see where the leak is coming from; yup, you can just take a look at it. However, there are electric leak detectors in the market that can help you if you are feeling a bit lazy today.
Compressor not turning
A clutch that does not engage causes the compressor not to turn, making the entire air-conditioning assembly to fail. However, in most cases, the problem is not really caused by clutch itself. If you would do a simple jumper wire test on the clutch, chances are it is still reacting. The usual causes of a faulty clutch are a blown or broken fuse in the assembly as well as disconnected or broken wirings. If these are the cases, a simple replacement would get you your AC system back.
Another reason for the compressor not to turn is the lack of lubrication. In most AC compressors, there exists a low pressure safety switch. This is a device that prevents the compressor from turning if the refrigerant level is too low, protecting the part from any further damage. And as you may have already have guessed, the only way to solve this is putting in more refrigerant.
However, you would still need to know what caused the refrigerant level to go low. Chances are: (1) a tube in the assembly is blocked, preventing a proper circulation of the refrigerant and oil; (2) there are holes causing leaks; or (3) you are using a wrong type of refrigerant for your AC compressor. Finding out which causes your car's AC to fail is only a matter of examining the assembly. If there are no holes and no tubes are blocked, then you are using the wrong refrigerant.
