Hey everyone. I realise this is an old thread, but I had the same problem. Ken, I nearly fell off my chair too when I read your answer
about the cruise not working as well. Anyway, I read all the posts on the subject and decided to have a look under the bonnet again.
To my joy, I found a small rubber pipe had popped off of its connector. I dont have a clue what it does, or what its called'
but air blowers and cruise are working just fine now! Id just like to thank you alk for your informed answers, and indeed questions.
I have attached two pics to show the location of the offending item. Hopefully they will help other hapless amateurs
such as myself!
