Issue with Aircon on Fabia VRs 55 plate - need expert help

[Chr15py]

I have put this in the freedom "ask a tech" area also but thought it best to put this hear too invade it is missed.

Ok so I have a real issue somewhere with my Aircon and need some advice.

Earlier in the year I discovered that my aircon rad had a hole in it so decided to go for it and get it replaced. That was changed for a new one but the aircon pump wouldn't turn. The garage said that they think it's the pump so I said forget about it and I'll source one. The long and the short is after specifying the exact model number from 20 online breakers and 10 apparently correct pumps, we couldn't get the right one so I got a new one from VW. Problem fixed...no. It still won't turn over. The garage even got someone super special on that said it was a level sensor...that got changed and still, not working.

It's enables on Vagcom and should be working but it just isn't! Any ideas guys and please, keep it on topic :(. I've spent far too much money and just want it sorting!

Thanks in advance

It still won't turn over.   please give more info.

 

Do know and expect u do that aircon requires regassing and this also has a lubricant for the pump.

 

If pump has been run without being regassed then it can seize.

 

Pump has a 'breakaway' clutch which will 'break' if seized.  ..

Is there power getting to the compressor?

Cheers for the reply guys. Where we're at:

System is fully pressurised with gas.

Compressor is new alongside the pressies sensor.

It's is apparently seeing signal - I'll double check that when they open.

Aircon buttons inside the cab light up when depressed.

Car drives as you would expect it to. The revs don't seem to change when you turn the air con on though.

Appreciate the replys guys

when selecting AC should hear pump engaging and slight drop in revs.

 

Aircon pipes inside engine bay will get very COLD if compressor is working as norm.

 

Take care when touching them.

 

If not cold then no Air Con.

Aircon is definitely not working but it is fully gassed with new compressor and condenser. Light comes on when you select Aircon but no Rev drops

Low pressure switch?.

does radiator fan run as this is used to cool air con radiator.

had a golf tdi with twin fans that never activated.

was the small fan at fault.

same as you was fully gassed.

no VCDs errors and VW hadn't got a clue.
