I have just taken my Qashqai to my local Nissan service centre because my blowers and A/C are only working intermittently
I was told that my A/C unit need recharging and that it would cost me £160 and this would fix the problem
but I’m not convinced as surely having my A/C recharged wouldn’t solve the problem with my blowers
My car is still under warranty until November so I would hope they are not trying to rip me off!

correct even if your ac was empty of gas your fan/blowers would still work as many qashqai owners including myself have found out with the condenser problems . I would have another word with the garage if I was you, hope you get it sorted

The blower is a single fan that is controlled either manually or by the system. Does the blower blow correctly on the speed button...low to full air flow?

Air conditioning depends on a number of things. Blending cold/warm air from inside or outside the cab.

What do you mean by intermittently?

The blowers will work at different levels but only for 2 or 3 minutes then cut out completely

Does that happen with the Aircon switched off...heating only ?

It goes off with the heating on but seems to happen much quicker when I use the aircon

Unfortunately there is no single fault in diagnostics that relates to the Blower stopping after some short time. Life gets quite difficult here because a number of sensors control vent output temperature. Also, the blower has an electronic speed controller which is driven by the result (sensing) of the sensors and user demand. I think the heating blower stoppage indicates a problem that is not to do with lack of refrigerant.

Diagnostics is quite lengthy and requires Nissans Consult test/diagnostic tool to determine sensor performance and electrical/electronic working states. The system could have stored DTC's (error codes) which need to be checked.
