So the old GQ TD42 has been having an issue recently whereby when first starting the car, though the AC kicks in, the cabin fan does not blow on any speed. However, when you drive down the road a bit it comes on again. At first i though it was the fan resistor so i replaced it with a new genuine Nissan one but it has made no difference. Anyone else experienced this and know what it might be? Dodgy earth, burnt plug ???? Thx
