Hi Guys!

My A/C stop working completely. I checked the resistor, the climate control, the blower and everything is fine.

Then I decide to check the refrigerant. Nothing at all.. I tried to charge using a regular refigerant can and I could clearly hear something leaking near by the compressor even with the engine off.

Before I change the compressor and ruin my pocket, I will bet in change the compressor seals.

The question is, have you guys tried that ? How hard is to access the compressor ?

 

to remove the compressor :

 

So, back in the 70's, I worked in a factory that built home window and automotive air conditioners. One of the significant things I learned was that the refrigerant used was mixed with oil to provide lubrication to the compressor/pump.

So, my question: If 'all' the 'freon' leaked out, and you get the leak fixed and then recharge it with Freon - does the Freon have lubrication oil in it? Or do modern systems not need oil in there?

Iv often wondered about this. See, it seems that "recharged" systems often fail in time. I've always wondered if a step is not being missed here. Does anyone know?

 

Mark, you must :
1. repair the leak.
2. pull a vacuum on the system for at least 30 minutes to remove any moisture ( 2 hours is my choice )
3. feed in the proper amount of R134A ALONG WITH the recommended quantity of 'PAG' oil. ( with the compressor running )
( Usually, one of the R134 cans is one marked "with PAG oil" or "with compressor oil" )
