Hi Lex,
Good luck tomorrow to you too.
My fan decided to stop after about 5 hours. I called out the breakdown people after the fan was on for at least 3 hours solid. They took a little over an hour to come and of course when he arrived, the fan was silent, car started perfectly and the fan didn't come on at all.
Now this could mean the fan is now fine (yeah right!), the switch is slightly faulty, then car / battery has some kind of sensor that worked out the battery was too low and killed all power going out, (I know lots of clifford alarms have that kind of intelligence) or any one of hundred of other things. I did drive for about 20 mins with the air con turned off after the first 3 hours of the fan. Some of the posts thought the two things might be connected. When I stopped initially, the fan carried on for about 2 more hours.
I shall see how things are tomorrow and perhaps try turning the climate back on to see if that kicks the fan back into life. I will also post here anything I find out, and I'll see if I can find someone to look at it. Audi Harold Wood are the obvious choice being near to me but I shudder to think of the cost...
Good luck,
Duncan
