I changed my loom from zr 105 with a 25 loom with air con to be able to have elec windows n elec mirrors. Change over went ok except with realising I had to change key barrel aswell. But my only problem since is that I swapped the rads over aswell as air con one was newer but since then my fan hasn't kicked in at all. I've tried changing the black sensor on the elbow. Made no difference. Fan does kick in though when taking plug off........... Any ideas anyone???? help please.....
