The rotary control knob that controls the fan speed, on my Wife's Micra (1.3GS), no longer functions correctly.

It now only works with the two extreme settings, off, and maximum fan speed.

I have tried to get access to the switch, or whatever is attaches to, but accessibility is a problem.

What is the cause most likely to be, the switch, connecting cable, etc. and what would the procedure be.

Any help is appreciated, thanks.

sounds like the resister that stems the flow of electrics to slow the motor down
look for a box the size of a box of small matches behind ish the glove box with terminals coming off and going to the heater box
sorry never done one on this car

As BB suggests. Sounds like a failed resistor pack.

Very common fault on all Nissans.

From the passenger footwell, look up behind the glovebox.
Remove the 4 way connector.
Remove 2 crossheaded screws either side of the connector.

The resistor pack will pull out. Looks like a credit card.

Either buy a new one - £30-£40 from Nissan.

Or, if you have a soldering iron, scrape each side of the 'blob' to expose the copper track.
Add solder until the 2 sides are connected.

I have heard that it can also be fixed with a heated screen repair pen.
