Blower Resistor : Where Is It

[mickrochip]

 

 here are two photos of my blower motor , the two outside terminals are back ,red, 

while the two inner terminals are green ,brown /purple     

 the red black wires have no power in them, but when wired direct the motor works fine  please can  any one tell me where the red ,black wires terminate., a wiring diagram would be very  useful please

 do notwant to remove  the complete dash  

            any help will be greatly appreciated    thanks

My blower resistor is on the passenger side of the heater box and is just clipped into the housing

Maybe to help other people thinking of replying, you have already established the blower resistor is not separate from your blower and is built in to the blower itself.

 

Links to your other topics on the same problem. If I get time/can be bothered since it will need maybe half an hour, I will lock all these and put links to this topic, otherwise people could end up replying to many topics which are all the same and not see the end result once the problem is fixed. It would have been preferable to have continued on one of your existing topics rather than starting a new one.

 

It seems as if after at least 1½ years you have still not managed to sort the problem and got the blower working. I think if it was me after all this time I would use a dealer. Since you will not have been able to use the air con with the blower not working, the air con seals will probably have dried out and the refrigerant leaked out so without spending many £100s it will not work again.

 thank you all very much for your information.

 I now will be looking for a relay or a fuse ,,or could it be a possibility of the air con  leaking out

     where does the red black wires go to or where are the relays sited  

  please reply asap  

 P.S a wiring diagram would be very useful

                            

                                       thanks    mickrochip

just checked ac  refrigerant , all seems ok pressure wise,but ac  compressor not switching on, could this be a  

sensor , by the way where are the sensors located

                           thanks

Have you tried a replacement blower since the one in the pictures has markings on it that a scrap car dealer might put on ?

 

The air conditioning compressor will not run if the cabin blower is not already running. So this does not mean any of the pressure sensors checking the refrigerant are faulty. What pressure did you measure for the refrigerant, should be about 4 bar on the low pressure side if there is enough refrigerant to start the compressor, but if there is not enough refrigerant the compressor will not continue to run as the high pressure after the compressor will be too low. The high pressure sensor may be on the condensor where the pipe from the compressor joins. I do not know where the low pressure sensor is, possibly it is on the compressor.

 

In the Haynes manual there is a typical wiring diagram for the heater blower but the wire colours do not correspond to yours, I do not know if you have looked at this diagram in the Haynes manual to see if it helps. It gives wires going to the blower

- from the heater control panel blue which splits to brown to the blower motor and black to the resistor.

- from the blower motor white which goes to green/yellow and then earth.

- from the heater control panel grey which goes to the resistor.

- from the heater control panel blue which goes to the resistor.

- from the heater control panel green which goes to the resistor.

 

The controller takes feeds from the engine fuse box, the bsi and the instrument cluster. it also connects to the diagnostic socket which would allow a Lexia to check the heating system.
