Hi all, I've just replaced the blower motor and resistor on my newly purchased xtrail T30, I've had the whole unit in and out numerous times now, ensuring the top and side intake/outlet routes are lined up ok. The unit is sealed, but once is all back together, the fan spins really well but airflow is shocking. The only obvious thing I can see is there is no filter, would this affect the airflow??

State the year, model, automatic or manual AC/heating system. The diagnostic procedures vary between the two types. The first thing to check is the operation of the input door motor that's on the air box. For you to perform the various diagnostic/repair procedures, you should download a copy of the FSM for your vehicle from this site:

Cheers mate.
It's the 2007 xtrail t30, it has air con.
I bought a brand new motor and resistor.
I've added an air filter today and airflow is still poor. The fan sounds like it's spinning at full bore but there isn't the airflow to accompany this

Cabin air filter will not increase air flow. My guess is that the new motor is weaker than the original Nissan one. That was the impression I had when I changed mine with a new aftermarket one, but it works fine and is quieter so I cannot say for sure. Blocked blend door? Is it possible you did not properly tighten the blower cage so its not spinning as it should. If yours has climate control the system is capable of running a diagnostic. The procedure is in the service manual.

Diagnostics seem to show no issues, my guess then would be a poor quality motor. My issue with this tho is that the fan noise sounds like a lot of air is moving

What type of motor did you get, and did you do the replacement yourself? I bought one off Amazon that was the same as was featured in a how to replacement video on Youtube. Works fine and it is very quiet..

Well you are a champ if you found it easy first time doing it. This is the one I bought.


Obviously not available at the moment, but I have been pleased with it. It is very quiet. I did note that in some reviews of this and other motors people sometimes complain they are noisy. I am not sure if some are defective or badly installed. Bit of a pain to take it all apart to check. You have my sympathies.

Cheers dude, well when I say easy, it was straight forward, the theory is easy. The amount of force required to get the old motor out, well...let's just say I skipped arms, back and shoulders day for that week 😂😂😂

What exactly is the issue? In this case, it would have been a weak new blower motor fan. There have been lots of threads written here and elsewhere on replacing your blower motor in the Xtrail. There is even a video how to on Youtube.

Yeah I've already replaced the blower motor fan, and the air flow out is v v weak. It fixed the initial problem of the fan not working at all.

The fan audibly sounds like it is working properly, ie changes volume between different levels. But it doesn't feel like it is pushing much air out at all, and it's air flow barely changes with the different levels.

So in short - sounds like it's working - but barely any air coming out.

Looking intensely at the manual - thnking it could be an issue with the air mix cable... does anyone know how to access this? Does the whole dash need to come off?

First of all, is your AC automatic or manual. There's a major difference with the air mix door operation. Here are two pictures explaining the difference:

Automatic air mix door

Hey there

Yep those are what I have been looking at, but wondering where in the car they are actually located ?

I have a manual system.

There's one by your right foot.
Pull the small panel besides the accelerator pedal.
To get access to the right side it s better to get the glove compartment out.
Take a look at this
