Aircon regas ?
 
After my earlier thread about air-conditioning not working I've now replaced the fan and resistor.
I did not disturb the air-conditioning circuit and the fan is now working but its not blowing cold.
It had a regas a few months back and was working fine until the fan went
As the system probably overheated before the problem was found , will it need regassing again or could the condenser be at fault?

Probably only coincidence.---:shrug:

Did you have your Air-Con leak tested before getting it recharged ??

Must have had a leak that needed fixing because of the first loss of gas.

Russp 22nd May 2019 20:44

It was working OK for a few months
Do they not leak test the system when regassing ?
The condenser looks a bit ropey could this be the source of the leak?

It is usually the condenser Russ, drop Jules a PM, he stocks new ones.

Not looking forward to taking it to bits again !

Depends on who did it, I have heard of numerous places just putting some gas in to put some cash in there pocket.

The other problem a lot of places like Halfrauds and Kwik Fit have people who don't know how to use the kit so they just plug it in and when it warns there is a leak they just override the warning.

As soon as the ambient air temp goes above 20 degrees most A/C engineers are flat out so if you want it done quickly you pays your money and take your chances.

To do the job properly takes about an hour.

Just had mine recharged at ATS with a Groupon voucher, mine lasts about 9 months before becoming ineffective there was 150g of gas in the system new it's about 500g I just get it filled every year

But talking to the chap who did it and he says the machine does a vaccum test and it's possible some pin holes are pulled closed so no leaks but the system when under pressure can force pin holes open , he didn't say why the machine didn't do a pressure test , but I think some air con specialists do?

To do the job properly you should do a pressure test with Nitrogen and a vacuum test, if either are not done you are not doing it correctly.

Not heard of the pin hole thing before but every day is a school day, it is usually seals drying out, a failing hose, joint or component.

Any car that can not hold its charge for at least 18 months has a leak that needs fixing, I have worked on cars that still have a good charge of refrigerant after 10 years and they still work.

If a recharge was several hundred £'s I suspect a lot more cars would be repaired or have no A/C.

The condenser looks pretty rough a lot of the fins have dropped out presumably as a result of it getting hot with no fan so I've ordered another one

Both of mine have required a new condenser due to deterioration and small leaks - I'd guess there is a good chance you require one.
