Re: blower fan
Hi mate,
It seems that your fan selector switch may have melted or short circuited.
This has happened before to a member of our forum and you can read about it HERE
I would advise that you take a closer look at the fan speed selector switch to see if it has fried or not.
Since the fan itself is stuck on one speed, it should be working fine, so it the fan speed switch that must be causing the problem.

Re: blower fan
Ah I may be able to help here for a change!
It's one of two things;
If you can only get the fan to work on the 4th speed setting (i.e. the switch will not work for 1, 2 and 3) then your resistor board (may be known as temperature controller)is faulty or simply broken. The resistor board is used for 1,2 and 3 speeds and is simply a bunch of resistors to drop the voltage supplied to the fan. The fourth speed setting drops all 12V on the fan. Incidently, this is a flaw in the design because there should be a relay in there to prevent the huge current drop on the switch which could cause it to burn out which leads to the second possibility...
The switch has burnt out, which is all detailed in the link Jalal posted above.
A simply test to see what problem you have is to put the fan on speed 1 and see if it works, then 2, then 3 and then 4. If it only works for 4, you have the first problem. If it just works on full the whole time, no matter what position it is in, stop using it immediately! The switch has burnt out and is taking the full load which could end up disastrous for your wiring. If you can't get it off, belt it (worked for me) or simply pull out the fuse for the blower motor.
I MIGHT have a spare temperture controller board which I purchased through a wrecker while I was fault finding mine. Check with Nissan to see what prices they offer. Otherwise, send me a PM if you need it!
The switch will set you back roughly $120 unless you have a family member or friend who can get it at trade prices... I ended up getting it for $80.
Hope it helps!
Edit: Sorry, in my excitement at the possibility of being useful I didn't read your original post fully You definitely have a problem with the switch. As in the link, you will need to get that back portion of the switch from Nissan (or a wrecker). It is a very easy job to replace it - and I know this because I did it myself and I'm by no means handy in any sense of the word.

Re: blower fan
Hi Ray,
Can you please post the part number of this thing and I'll try and track it down for you and see if I can get it any cheaper.
