Heater Switch Not Working

[bluecarwayne08]

Have a problem with heater switch on my saxo which ever setting is used it will not work can it be the heater motor if so will the dash have to come out?

 

Any advice would be welcome

blower motor is situated on the right hand side of dash and accessed from underneath dash. First check would be to confirm if voltage is being recieved at the motor electrical connector......it should have 4 wires i think......one is and earth and the others will supply voltage that will vary dependent on the position of the heater switch.

 

If there is voltage going into the motor and a good earth i would suspect the heater motor has failed.

 

If there is no voltage at the heater motor i would make a check on the ignition switch connections......if memory serves me correctly you need to check the 2 pin brown connector.....for the heater to work you need 12volts on both wires.

 

Dont forget the engine needs to be running for the heater to work.
