Hi everyone, i was hoping someone might be able to help with this one,its actually on my fathers car,which is a citroen but still french.....lol, he has a 2001 xsara 1.9 diesel...he has just noticed that the A/c is not working,took it to a main dealer for regassing and was told 90 euros later that he needed a new compressor.....(750 euros)as he has a leak somewhere and its not holding pressure, i'm not really familiar with these and wondered if they could develop a leak or could it just be somewhere else on the system? i'm not sure if uk and french models use the same parts but i know it would be alot cheaper to get the parts here(uk) and fix it on his behalf....thanks in advance for any imput and appoligies for using the site for another brand....

Greetings Matt....i would be inclined to take thew car along to an independant A/C specialist and have a leak test done.
Most A/C systems all work the same but it is almost impossible to find the leak unles you have the right gear....there is really no easy way around this.

And don't worry about mentioning another marque...they are all made by the same company

Cheers,

Thanks for that....i'll pass it on and hopefully he'll get it done....
Matt....most of them have a feature built in that automatically energises the A/C when using reverse or during warm up to lubricate the seals in the A/C pump for a short period......my wife's Peugeot 307 does.
All A/C's should be used regularly throughout the year for a minimu of at least 30 minutes to prevent the seals drying out....this is what causes leaks and dissipation of the gas in the system.
When the system is recharged, the gas should contain the correct amount of lubricating oil and a leak detection dye which is then visible under an ultra violet light tester used to detect leaks.
The A/C system in my 12 year old Jaguar operates faultlessly because i use it nearly all the time, Winter and Summer.
These days, most modern A/C systems absorb very little power from the engine, not like the old systems where if you engaged it on the move, it felt like shoving the brakes on! :^))

Cheers,

thanks for your replies,i have one more question if i may.....will the compressor "kick in" when the A/C is switched on from inside the car if there is no gas in the a/c's system ? i'm not sure if the car just has a leak somewhere or if the compressor itself is at fault...

Do what Peppipug suggests and find an Automotive AC engineer.
Modern days car AC system run on a mix of gases (R134A) and they boil off at different rates. If you have a leak the first one to boil off will escape first leaving you with a gas that will not cool properley.

There is almost nothing a normal person can do on these system now. The fitting for the gauges to read pressure are designed just for car, you then need all the other junk that goes with fixing and finding leaks, reclaim unit, nitrogen and nitrogen gauge, vacuum pump, fridge gauges.
