I'm new to these Navara's.

I have a 2009 Navara Sport X and I have noticed during the cold weather that the left side of the heater isn't getting warm at any level or setting.
I wasted £100 taking it to Nissan for them to tell me that there is no fault on their scanner and it must be in the heater.
Is there an easy way to get at the temperature control flaps so I can see if they are seized or might it be something else.
Thanks in advance, Mark.

Welcome along :thumb2

I'd say your heater matrix needs flushing through.
MG ZT's suffer with exactly the same fault.
The bottom half of the matrix heats the passenger side & the top half the drivers side.
All the silt & sludge sits in the bottom of the matrix.
Try washing it through with the hose pipe & see what comes out. Try the heater again. If this helps a little or not at all. Buy some decent dish washer tablets & dissolve a couple in hot water & pour the contents into the pipe feeding the matrix until it comes through the outlet side. leave it to stand for as long as you can (I let mine stand for around 12 hours over night).
Flush through with the hose pipe again & this should have cleared all the crap.

Did they rule out the Thermostat then ?
