A/C compressor worth replacing?

Postby LoafFace » Mon Oct 29, 2018 12:21 am

Because the compressor starts clicking is it worth replacing it or does it just start clicking again almost instantly? Also what are some good ways to reduce it clicking? cause it makes the car sound unhealthy and I'm a bit of a snood when it comes to these sort of things.

The clicking noise would be the clutch engaging and disengaging which is quite normal. If it is clicking constantly it would be worth seeing an aircon specialist to check it out.

What about if the revs are spiking to 1500-1750k when the pump engages? They do drop again after a few seconds. Back story is, I cleaned out the throttle body and now the car and TPS are on speaking terms again, the air con engaging causes the revs to jump up. I confirmed by running with air con off and problem didn't persist...

Drive round with the a/c on for a while. The car still needs to relearn throttle settings while the a/c is operating

Cool, I was going to take a can of MAF cleaner home too, I've done around 160Km since the clean, varying degrees of driving, highway, stop start, residential etc. hopefully it'll calm down soon, its a pain when trying to stop at lights and the car is trying to take off still...

When was the last time the AC was serviced? It can do that when it is getting low on gas. The regassing includes the lubricant, which is why you should run the AC occasionally even in winter.

Be careful with the regas though, there are lots of different gases and many of them can damage the units. Just hope you haven't had someone do that to you in the past otherwise you will need a new compressor. One of the stupid ones to use I think is LPG, it works and is legal but stupid. A leak or fault could result in fire, and LPG is too drying even with added lubricate and causes damage.
I might add a pic of my car once I style the exterior a bit :).
