Blower NLC

[craigs135s]

The blower in my pug only works on number 3and 4, 1 and 2 are non-existant any reasons on why this would be? Is it a case off pull one part off to fit a new part or could it be a number of things?

Cheers

Depending on how the speed control works it could be wiring or the resistor pack. The resistor pack may or may not be a separate part on your car - they can be embedded in the blower unit itself.

I would start by finding the blower, finding the wiring that runs to it and see if you can see a resistor pack (in this case you're likely to see 4-6 wires running to the pack). If there are only two wires running into the motor, the resistor pack is either elsewhere, or the speed control is being done with a proper speed controller circuit - either way you need to trace the wires back towards the switch - there will be a black box inline in the cable somewhere that has the resistor pack or speed controller.

- if the heater blower only works on 3 then it must be a problem with the heater resistor block. On 3 it bypasses block and supplies a full 12v to motor on the 1&2 it steps the voltage down to slow the fan.
Hope this helps a little

from exiges.com - robin is right once again

hi have a blower problem. it only blows warm air. not sure how long or expensive controls are to replace.

Thanks Robin. I will get someome to look at it for me.

Scottishelise isv the problem with your elise??

Scottishelise -

it depends on which car you have - assuming no aircon, S1's were all cable operated flaps - the heater matrix is always in the cooling circuit and a flap directs air to the cabin either from the matrix or from the fresh air.

K-series S2's use stepper motors to control a similar mechanism.

I think most of the toyota engined cars have air con, and I would guess the arrangement is totally different for these, but never looked, so don't know.

So, what car have you got?

Cheers,
Robin

Anyone else read blower and expect supercharger? Or is that just me?

to be honest, something completely different came to mind
