Forgot to say that before recharging the system at the second time I have evacuated the ac system and left the vacuum pump running for about an hour just to get rid of as much moisture as possible. On top of that the garage also pulled vacuum.

Hi,
I have fixed the ac a long while back I only did not give an update here so I do it now.

The car we talking about is a 2001 Peugeot 307 that has a market value of around £500 or less.
I wanted to get my aircon fixed but did not wanted to spend silly price for doing this.
I though if I can’t fix it cheap enough then I may just use the car without ac or sell it as is and add the cost of professional ac repair to the selling price and I’m not far off of a price a younger car that has a working ac. So this is what you need to know before judge my way of fixing this ac.

I had gas in the system still but because some people suggested that it may only needs regassing and I was not absolutely sure what’s wrong I took the car to a garage to get it recharged. They had a “recharge or no charge” policy I had nothing to loose as if it doesn’t work I don’t have to pay a penny. And yes… no. Id did not work. They have removed all refridgerant from system before I left and yes it was all free of charge.
Next step was to remove ac pump. I have hooked up my gauges to the low side and high side ports and where the ac pump was i have covered one pipe with my finger and blown shop air into the other creating some pressure in the ac system. Both gauges changes togethet without any kind of delay and when I lifted my finger from the pipe I was holding the air was flowing freely through the system and both gauges dropped to 0 in the same time.
So at least I knew there is no blockage in the system. I’ve bought another used ac pump for £15. It was a bit of gumball as at this point I still couldn’t tell if it’s the pump that is failed or a valve in the system or a blockage that is unblocked in there but the dirt is still in there and will fail again. But I thought that’s it if it’s not the pump then I won’t be bothered to go any further.
Repaid manual of this car doesn’t want me to replace receiver drier when replacing ac pump so I have skipped this (probably I would do if the car would cost a lot more but this is a kind a end of life car). And the cleaning out of the ac system has been skipped as well as I could not see any dirt or metal bits in the old pump.
After replacement pump fitted I went back to the same company to recharge (but another location) and after charge I had ice cold aircon. Yuppie
Now I know this is not the proper way to fix this bur a professional ac repair would probably cost more than the value of the car. So please excuse my technique.

As mentioned above.. yes it does turn on.
I think I’ve got the answer now anyway.
I’ve spoken to a commercial fridge service man today. He told me this is definitely my compressor.
So I gonna replace it.
But this forum may will be helpful for people who looking for the answer.
So if your low side and high side pressure nearly the same then most probably your a/c compressor is faulty.
Dont forget to flush your a/c system before installing the new compressor!
