Hi I have a Grand voyager 2009 and the front heater blower is not working , i have 11 volts at the Resistor module but nothing coming out , ive just bought a used resistor module and fitted and still the same problem … either some one has sold me a faulty unit or am I over looking something else ? I've tried looking for the blower relay for this but the legend on the fuse box cover doesn't appear to mention one it just lists the rear blower Has any one else had this problem ? Thankyou
