Last week my cigarette lighter stopped working. I found that fuse 29 was blown and so replaced it with a spare. A few days later it has blown again. Is there anything I can check myself before getting it booked in at a garage?
Yep sounds as if something in-line is definately blowing it. Or you may even have a short somewhere in the cabling. If you disconnect everything external you have plugged in, I would get it booked into the garage.
