Re: Renault Scenic I - Heater Fan Fix

as per peoples instructions about resistor pack, the first thing to check is fuses and mine were all ok, rather than pulling the dash apart just to check something that may not be faulty if you have no blowers at all unplug the connection in passenger foot well (red and black wires) put a volt meter in the terminals coming down from dash (remove white insert on plug) with ignition on and fan switch on 0 place meter on terminals when the switch is moved to position 1 you should get 12.1v and as you move switch to higher positions voltage will rise but not by a lot, if you have voltage on all positions then its the motor at fault not the resistor pack. could be water ingress from air intake as there is no cover it just goes straight to the motor or it could be clogged by leaves and other junk its sucked in, remove blower motor and try putting 12v straight to motor if it wont run replace!!!!
