Hi guys, have browsed the FAQ but i have to be honest computers arent my strong point so i appologise if the answer is in there. we've got a 54 plate scenic 1.5 diesel (100) and recently the fan speed setting only on number 4 has stopped working all the rest are fine. now i know there is a known issue with some of the other speeds (resistor pack i think?) but no-one seems to have mentioned just on number 4 (it was my understanding that number 4 setting bypasses the resistor?) can anyone please help to troubleshoot my problem so that i can locate the correct part on flea-bay or some other location. thanks very much, Rich.
