    Heater Fan not working

    I have an OG 9-3 2002

    I'm hoping someone can help with an issue I'm having with diagnosing the heater fan (blower). It recently stopped working completely. I removed it and inspected and tested it by hooking the two wires to 12v. All working. Did some further research and read alot of problems with the ACC fan module. I got a (good, presumed) working second hand one. Still no fan action. Does anyone have the pinouts/wiring diagrams or some fault finding tips before I potentially go and buy a brand new ACC fan module to try.

    Thanks

    John

    Have you checked the sensor in the front grill?

    No I haven't. What sensor is that? And how should I be checking it? Thanks!

    Heater Fan not working

    Itís an outside temperature sensor. Is the temperature showing up on your sid display?

    Also there is a resistor pack that controls the fan speed which is prone for playing up.

    I can't tell if the temp sensor is working as the SID display has the usual issues with the cable. Resistor pack wise, mine has ACC so it doesn't have one of these and has the fan speed controller module instead.
