I need to change the aux belt on my 95 2.0 petrol with air con. Is it easy? and secondly, air con stopped working. I have manual air con, push the button, light comes on, but nothing happens?. I noticed that the 30 amp, 3rd position blower (??) fuse in the aux fuse box under the bonnet had blown also, changed it and seems to make no difference to anything. Any ideas on both please. Kev
