SOURCE: the ac compresor it dosen't start.pression is fine

It is unlikely that a fuse or relay is the culprit. It is more than likely you have a controller issue. Either the ECM for the cars computer or unless there is another controller for just the air conditioner. Not really good with newer stuff but just a thought. If your as cheap as I am you could run a test wire to the lead wire which locks the clutch for the ac compressor and starts the pump spinning to see if that keeps it on and pumps cold air for you, CAUTION improper wiring can cause more harm than good (short circuits, burnt electronics, and or fires) so be careful if you are attemting to rig this and put all the safety nets on it you can. A fuse, ignition on circuit, and plenty of double checking would be good starting points. I would not want to pay the dealer a lot of money but some times it is better than seeing your car go up in flames when you learned the lesson on how to do something correctly the hard way.

My air conditiner stop working in 2005 scion xb

Sounds like the clutch on the compresor unit is not working.

When your car is running turn the ac on and check under the hood you should be able to hear a click every few seconds, if you dont then turn off the engine and take the key out.

If it don't click, look for the wire coming from the compresor unit towards the wiring harnes there should be a plug check for corrosion inside the plug.

If it does then go to any auto parts store and locate the ac refill bottles and follow there instructions.

Hope this helped you.

If it does click th

I have a impala 2005 since I recharge the ac system,the compresor goes on and off.

That is normal behavior. As long as the AC is cooling. When it runs it builds up some pressure, then pauses running as the pressure bleeds off providing the cooling. When pressure drops to certain level it kicks back on.
If system was low on freon, then it may have run somewhat continously if there was not enough to build up reserve pressure.

Look at the compressor pump when it is stopped, in front of the puley is a clutch like affair, start the car and look to see if this clutch is spinning if it is your compresor is engaging. Also most times you will hear a change in engine sound when thecompressor engages

Front & rear ac is "ok" on high RPM but on low does not cool at all,I'just change compresor. Is it any filter in those lines,maby.

Theres no filter for the rear a/c lines, the problem is the lines themselves are too long. On low speed, by the time the cool air reaches the rear vents, its already warming up again.

Ac compresor clutch

this isn't easy and you will need special tools.  You will most likely need to have the compressor on a work bench.

The ac in my 95 Jetta just works while the car is cool, then it stop

In addition to what emission wiz says, observe the speed of the fan when you turn on the a/c. some fans, when the are cold they run faster, then they get hot and slow down a lot. Also check that the small belt that drives the second propeller is ok. And for last, check that the front of the radiator is clear of any garbage, like a plastic bag that might have been cought in front of the condenser with the wind. If all this is working properly, there is nothing else that could be happening machanically to this a/c to stop it from cooling. look at the center of the pully of the compresor, make sure the entire thig is spining when clutch engages.
