The blowers to my windscreen and other blowers around the dashboard stopped blowing but the two blowers below worked fine. All displays on controls were fine and the fan was functioning also. After a week or so I booked the car into a garage for them to have a look and would you believe it, before the car went in, it all blowers started to work again and continued working for a couple of weeks. The top blowers failed again while the blowers below continued to work perfectly. I booked the car into the garage again but after having a preliminary look said they had never seen this particular problem before and asked to have the car for several days to investigate. They are planning to do a very long and I believe costly investigation as they have no clue as to the cause of the problem and have never seen it before. The car is low milage 55000 and not driven very much - not sure if that is significant. I have seen lots of problems with the fan and all blowers failing on thr forum but none like the problem I have described. Because the blowers kicked into life again after the initial failure, there may be a bad electrical connection which could be very difficult to find. I am reluctant to let a garage loose on the car without understanding more about what the problem could be. Before booking the car in I would be really grateful for any help or information from anyone who has experienced the same problem.
