T31 Blower intermittent operation.


Car is providing intermittent power to the fan switch.

I have had issues with the blower not running sometimes and others running fine on each fan level. I first removed the glove box and checked the connection to the blower which was fine but I wasn't getting any power registering and it's darn hard to test the connection with just the standard poles provided with the multimeter.
I removed the radio fascia and unplugged the switch. Initially the power wasn't here. Then I turned it on again and the power was there. As seen in the video power is there for 5-6 turns of the key. Then it stopped, no power coming through. Fuses are fine.
An auto-elec mate suggested getting a wiring diagram but I haven't had time yet to check if our ESM has a wiring diagram but if anyone has one they could provide or any ideas please let me know.

Since you have an ST it could be the manual fan speed switch having an intermittent contact from age or a fan speed resistor on its way out.
Yes, the ESM has full wiring diagrams along with instructions on how to access and remove all components.

Re:


It's definitely not the fan switch - if you're referring to the fan speed selector switch.
The ESM seems to have a diagram and diagnostics for an Automatic Air Conditioner but not for the manual one in an ST. From what I recall reading in the other threads the ST doesn't have an Auto Amp?

Re:


My mechanic has quoted about $900 for a blower and resistor replacement. Does anyone know the part numbers for a 2009 T31 ST? I rang my local Nissan dealer and their policy is to not give out part numbers.
I searched the forum and I have found part numbers but I don’t think they’re for a T31 ST, only TI model or T30. Help me save some money please!

Re: T31 Blower intermittent operation.


I managed to remove my fan control amplifier - what I believe that people call a resistor, or it has the resistor on there.
The interesting thing is mine doesn't look like the T31 one, white with a square-ish plug. Mine is like the T30 version, black and long. I've ordered it from my local Nissan for $[sign in to see URL]. Just to be safe that I am getting the right part. Hopefully I haven't shot myself in the foot and accidentally ordered the wrong part.

I also managed to remove the blower. The little clip you're supposed to pull out before you turn hurt. I got quoted like $550 for the assembly. I will likely try to find one online. I was also intending to do the bearing replacement found on the T30 blower thread. Not so hard to get to and remove. Putting it back might be a problem, I'm pretty big and the space is pretty small.

:edit: found the motor assembly part number here in the forums, my part number is the same, managed to get it from Nissan.
