Hi everybody, I'm hoping somebody in here can help. My friend has a 2007 Autotrail 634 u , and I do minor servicing and repairs for him,. at present his fire in the habitation area is fine, but the fan wont come on, also the extract fan in the roof isn't working. I've checked the fuses in the main block , and they're all ok. Anybody know if there are any other fuses that might have blown. Thank in anticipation, Sjflorton .
