Hi everyone,
We bought a WQ last year in the winter and obviously didn't test the A/C properly because while it works fine (so far), the compressor is very noisy. Sounds like a dull rattle or really dry loose bearing, something like that to give you an idea. The noise only occurs when the compressor clutch kicks in - so completely silent running otherwise. So, a) Has anyone had or known of this issue before? b) Do you think it may only require the clutch assembly to be replaced? I've found on eBay that you can buy the clutch assembly alone from the USA for about $120 incl postage. c) On eBay it's possible to buy 2nd hand complete compressors for about the $175 mark + postage. Now I think with option b, if that was the issue and I replaced only the clutch assembly then I wouldn't need a full re-gas? However if the whole compressor (option c) is replaced then obviously a re-gas will be required. If I do have to buy a 2nd hand compressor - are there any issues with putting it straight in? Will new seals be required? Do the internals have any issues if it's been exposed to air (I only ask because pictures of new ones have plugs, which the 2nd hand ones do not). Thanks!

Most if not all the WQ's had a niggle with the air conditioning, most prevalent in the XR4's but it was due to Ford not filling them up with enough gas, but you may have an issue, but it could also be because it hasn't been used for a while!

I wouldn't buy a second hand compressor, if anything buy new, Ashdown Ingrams is an auto electrical store which does A/C stuff. Most auto electrical shops are licensed to do A/C work, I'd take the car there and see what they think. |

Cheers guys. Didn't know anyone replied!
Yeah a gas refill would be a cheap solution, but a waste of time and $$ if it isn't the issue. Alright, new compressor sounds the way to go rather than 2nd if it comes to that.

So I've been thinking more about this lately whilst in the midst of an Alice Springs summer and I've noticed that once the compressor clicks on - it doesn't click off and disengage the clutch like it should periodically. The temperature coming from the vents just doesn't seem cool enough compared to other cars and the only way to disengage the compressor clutch is to physically switch the A/C off via the dash button.
The reason I'm now posting is that I've inadvertently read that another person was having the same issue with the clutch staying on and it came down to low gas and subsequent low pressures the compressor was trying to build up. He had the gas topped up and problem solved. So I'm thinking that maybe Twinpiston was on to something? It might not stop the noise, but it could stop the fact the compressor remains on for as long as the A/C dash button is activated and the vent temperature is poor.
