You’re having a problem with the air conditioning system in your vehicle. You know a little something about these things, so you decide to try some diagnostics. Once you do some checking, you come to the conclusion that it’s probably the A/C compressor clutch. Now what?
If, in your vehicle, that A/C clutch isn’t engaging, what would you do next? Among other things, do-it-yourselfers will try to engage an A/C compressor clutch that doesn’t seem to be operating. But why would the clutch be giving you a problem in the first place? There are a number of reasons for compressor clutch failure, truth be told.
Let’s look at some information that could be useful when it comes to determining if the compressor clutch is a problem, why it became a problem, and what to do about it.
Is Your A/C Compressor Clutch Bad?
The most obvious sign there is a problem with the clutch relay on your A/C is, when you turn on your air conditioning system, the compressor doesn’t turn on. When the clutch is connected, it usually makes a click sound. No click – no clutch. For some reason, it isn’t engaging. It could be a bad relay, or something else.
If, from your A/C vents, you’re not getting any air blowing out, this could be another sign of a clutch relay problem. The compressor won’t operate if the relay goes bad and that means no cold air production.
A/C Clutch Issues – Causes
As stated, there are any number of reasons why your A/C clutch may be failing to engage. Here are a handful of them:
- Bad relay/burnt fuse – replacing the fuse may remedy the situation.
- Low refrigerant – refrigerant would need to be added to, hopefully, solve the problem.
- A/C compressor oil is insufficient – the oil for your air conditioning system’s compressor might need to be checked/topped off/replaced.
A/C Compressor Clutch – How to Jump It
Follow these steps to give your clutch the kickstart it might need:
- The clutch oil cable must be disconnected.
- Make sure there is a sufficient amount of oil in the compressor.
- According to the manufacturer’s requirements, make sure the amount of refrigerant in the A/C compressor is sufficient.
The clutch can now be jump started. Here’s how:
- Unplug the single wire connector at the compressor’s front side.
- To the compressor wire you just disconnected, attach a jumper wire.
- To the positive terminal of your car battery, you will then attach the other end of the jumper wire.
- This will help manually start the compressor.
Note: This can all be very confusing, especially if you just don’t know that much about A/Cs or car engines. When in doubt, have a mechanic or technician check out your A/C system/vehicle engine.
