Qashqai AC issue help
Discussion
Hi
My a/c stopped blowing cold last year. Garage diagnosed it as needing a new ac compressor. Had one fitted and nothing has changed. Blows air but warm or hot depending on heat outside when I hit Auto on Lo setting it immediately goes to max level and immediately auto cuts out and back to middle level. This stopped just after compressor was fitted but happening again now. Pure nightmare having paid nearly 1k and now referred to nissan for another diag next month. At a total loss. Any experience with this? Im not a mechanic but can test a few things if recommended. Ie fuses/relays filters etc. Actuator is unreachable for me behind dash i think

So when we picked it up and the compressor was fitted. We drove it home and continued to blow hot air. Only change was it stopped cutting out when we hit MAX button- at first. We took the car back and they washed their hands of it so only had it back 1 day. Today (only fitted 2 days ago) it remains exactly as before we had any work done. Hot air only and cuts out on max. Have lodged a complaint but will take forever. Can't even trust the original diagnosis was correct re: ac compressor. Must be another issue they never found but I'm at my wits end fighting it tbh

Yeh it is j11. Just hoping there's an answer as it was supposed to be a compressor and cud be a condenser. Minefield. Thank you for your help, hopefully nissan can help in a few weeks
I work for a Nissan dealer in the parts deptartment. 99% of the time its a condenser. We are doing at least 5 a week just now.

If so you need a new condenser.
The original condensers are crap.
The part has 5 suppersessions on it iirc.
The Nissan dealer will have replacement condensors in stock.
And the AC pipes that rub through and leak, although you would like to think the system held gas otherwise they wouldn't have fitted a compressor.If so you need a new condenser.

But there's also a lot of idiots who blindly rely on the vacuum leak check as a definitive leak check.....

Idiots is the word. Halfords absolutely useless and unhelpful. Small claims court if nissan tell me the compressor didn't need changing or the one they fitted was faulty and fitted incorrectly. Who knows. Nightmare
Now I see your problem.You took your car to Halfords!
Do a bit of leg work and find a decent independent mechanic or aircon specialist.
Going to Nissan is almost as bad as going to Halfords for an older car.
Many of them will just throw expensive genuine parts at the car and charge way over the odds for labour. Fingers crossed the dealer you went to put someone competent on your car!

This may not be big news but I thought it worth posting for others. The AC on my Renault Scenic stopped working. Re gassing didn't fix it. A second look found the compressor wasn't working ( oh ****that's expensive) but then the chap doing the diagnosis bypassed the car's electrical feed to it and connected it direct to a 12v battery. And guess what.. Compressor working. Next step was try a new gas pressure regulator switch. ( Or something called something like that. No change. The actual culprit turned out to be a faulty temperature monitor switch in the heating system that in the middle of a heatwave was telling the AC that the ambient temp was -2c. Switch replaced and all fixed. My very good and very experienced independent Renault specialist hadn't seen this problem before so I thought it might be worth making others on here aware.

This picture is of a MK2 ford KA, which is basically a fiat 500.
We regularly get phones from fast fits like Halfords where they have managed to connect the hoses not to the AC ports but to the fuel rail that you can see in front of the ports.
The moment the machine ingests fuel it's instantly written off and the garage needs a new AC machine.

Keeps the fuel cool though.
Google says "Halfords employs technicians who undergo rigorous industry-leading training programs to work on a wide range of vehicles, including hybrids. They are trained to service and repair all makes and models of cars, including hybrid vehicles, which require specialized knowledge for high-voltage systems. Halfords also provides ongoing training and development opportunities for its technicians, including pathways to become MOT testers. "

Had that on a capture and Alfa, it uses a temp sensor in the mirrorGassing Station | Home Mechanics | Top of Page | What's New | My Stuff
