Re: Grand Scenic 2005 1.6 - Heater Blower not working
Made some progress with my fan blower problem. Could not find any resistor as described in other threads, although Renault advise me it does exist for scenics with climatic control.
Anyway, managed to get the heater blower working by hard wiring directly to 12v. Eventually located the blower motor behind the glovebox - you have to remove the panels around the gear stick and then the centre console panel to get access to the glovebox panel screws. Once you remove the glovebox, look up and towards the driver side, there you will see a heavy gauge red & black wire pair that supply the heater motor. The connector can be removed but the contacts are located quite deep in the housing and I cound not get a connector in there. Decided to cut the red & black wire a few inches from the connector and then connected the red to the 40A fuse in the glovebox that supplies the fan in the first place (via the power control module) and I soldered the black to the earth connection on a spare cigarette lighter connector I had.
So now when you want to turn on the blower you simply plug in the connector to the cigarette lighter to complete the circuit- it runs on full speed but a lot better than no fan at all.
By doing this I am now quite sure the problem lies with the power control module, which is not easy to get at - any advice on this would be appreciated and I hope the above is useful to somebody else.
