AndyR Posted October 20 Share Posted October 20 Had the same problem with my Astra when I first got it. It too was the resistor on the heater motor . Replaced and all working ok. Quote Link to comment Share on other sites More sharing options...
Vauxhall Owners Club Posted October 24 Share Posted October 24 Totally agree with AndyR it is usually the cause but also check the wiring is not poor connection (wiggle the lead going to the motor and resistor pack when fan switched on) Quote Link to comment Share on other sites More sharing options...
