GeoregeLG. Are you thinking of the drier?

 

I have checked the compressor by "jumping" the relay and the compressor started at once so i guess it is either no refridgerant or it may be the low pressure switch

I suppose it is the the low pressure switch that is shown here with a white arrow in the picture?

 

Now jumper the pressure switch to confirm thats the only problem. It would be best to do that with a set of gauges on the system and disconnect as soon as you see the pressures. Don't run it low on gas for an extended period.

And as soon as i jumped the low pressure swiych the AC compressor started at once

 

Yes. Thats the accumulator/dryer and has the low pressure switch attached to a schrader port.

And now it is working except i guess ii is low on refridgerant so i need to refill

Looks like the problem is solved

 

You need to find the leak as well.

I have a feeling that it is located in the in the front of the car in the condenser. I might be wrong but..

 

Most sophisticated method is an electronic leak detector. Best old school methods - feel for oil residue and a few drops of dawn in a water spray bottle around everything with pressure in the system and look for bubbles.

If i am lucky there is only a "weak" o-ring. Thinking of the fact that the car had been standg unused for years before i bought it.

A friend of mine have a "sniffer" that detect leaks so will check it using that tool.

Looking at the connector for refill of refridgerant it looks like the connector that i have on my air tools. What is the connector called and is it the connector shown on the pictures below?
