climatronic blowers not working

[pgblues]

Hi there,

just fitted an ipod lead to the back of the stereo, which works well, i have now noticed that the blowers on the climatronic are not working, the dials light up but just no air, i have a 2007 tdi 170 bhp,

I have tried to he change the fuse but the owners manual does not relate to the fuse panels in the car

any help would much appreciated
