A/C Issue

[timiteo]

I have a good used compressor if you want to buy it.

Good to know, PM me how much you'd like for it. Thanks.

I was told that the seal on the compressor is gone.
So not too sure if a need a whole new compressor with seal or if I can just get the seal separately.
I assume it's a leak somewhere inside so the whole unit needs to be replaced.

Hi, can I ask how you ended up fixing this issue? Did you replace the compressor? If so, where did you source it from and have it fitted?
I am having similar issue. Definitely have a leak at the compressor.
As occurred with yours, my a/c began to only function well when moving, not well in stop-start traffic. Then it failed completely. Secondary fan still functioning when a/c turned on, but no gas left in the system.
Its too hot these days without a/c functioning. Would love to know an affordable solution!
Thanks. C

I have no ac on my vento, went to get regassed and compressor wouldnt hold pressure, going to risk getting one from a wrecker. Read online its a common problem and was told today if the aircon doesnt get used for a while they do fail, anyone know which is true?

I guess it is a common problem, we have just purchased a 96 Vento as Daughter No 1's first car. It is still in Melbourne with my brother's mechanic who is preparing it for me to ferry back here to Canberra. I am not looking forward to the 6.5 hours drive in January heat with an unserviceable aircon. Although that being said, my 97 Golf CL that I have owned since it rolled out of the factory still has its original aircon with its original gas charge in it and works fine.

As I have noted in your thread, I believe the refrigerant gas acts as a lubricant on the seals and the working components of the compressors. I was told to give the aircon a 15 min run every week to keep all the parts of the aircon unit lubricated.

Gas this time only lasted a month. One week car didn't get used as I was overseas. Came back to no gas
Oh well.
Anyone know if a mechanic is able to change the compressor if there is no gas in it?

[mattross]

yep, you should run the a/c once a week for 5 minutes for oiling the seals. I believe it even states it in the manual...

[stefcio007]

Are the compressors the same across all models?

[hamza]

As far as i know, no they aren't. My vr compressor had a sticker saying 6 zylinder and the CL i parted out had a sticker 4 zylinder.

Might add some more info since I'm still researching this issue. When the AC was fully gassed, there was a high pitched squeaking sound coming from the passenger side whenever the AC was on. AC was running great though nice and cool at the time. After a while the squeaking went away and the cooling stopped too.
I have checked the compressor clutch and it is visibly engaging.
Could something be slipping?

High pitch squeak - could have been the hi-low pressure value failing? Or maybe when the 2nd fan kicks on?

When you got the gas refilled, did they add UV dye?
