Heater Help (Only working on 0 and Max)

I've read Kelv's write up on how to do it in the newbie section...

Heaters only working on 0 and max:
this happens on a lot of Nissans from the period not just Almeras, the speed of the heater blowers is controlled by a variable resistor on a circuit board. This resistor is controlled by the dial and if it burns out the fans will only work on the first and last settings (e.g. off and max). There are acouple of ways to fix it, cheapest being to remove the heater card from the dash (the circuit board) and solder a bridge over it, or a new resistor, or go to Nissan and buy a new heater car (they’ve replaced the original design with a more up to date one now) which are around £30 at the time of writing.

Well mine has been like this for sometime...can someone just let me know where the heater card is please, i've had a look from underneath in passenger footwell and looked behind the glove box but can't seem to find it!!!

Do I have to take the dash out or what? Thanks :)

Knowing my luck i'm probably looking straight at it :roll:
 
its behind the plastic panel just above the floor in the passenger footwell, next to your left foot if you're sitting there.
 
brown plug i believe correct me if im wrong someone. 2 screws and it should pull out pretty easy.
 
Does it look like a dodgy credit card, white on one side and on the other, what should look like a circuit? I can't even make a circuit out on it cos it's that rusty! :lol:

Ok so when I solder over it, do I bridge each of the points on the circuit card together one to the other or go from literally one end straight over to the other?

Sorry for the sheddy questions :confused:

yeap you got the right card.

not sure on the soldering, never had one go wrong yet

I reckon I might just buy a new card mate cos this one looks shite...mind you it is 10 or 11 years old now so can't complain really!!
 
may aswell go to the scrappys and grab a few, p10, p11 and n15 ones are all the same, plenty of primeras in scrappys now, may aswell have a spare while your there and best of all their free :lol: (5 finger discount)
 
got a feeling k11 micras may be the same aswell, seems like every nissan of that period used the same one so theres plenty in scrappys right now.
 
All sorted!! Got one from a P10 Primera. Looks brand new.

The Micra ones do fit but they're longer as the Almera/Primera ones are wider.

Weird thing is though now 2 & 3 are the wrong way round on the heater settings. 2 blows more out than 3 but i'm not bothered they work! :lol:
