The heater was working in my Bmw, i turned the fan off a couple of days ago and went to turn it on yesterday and it wouldn't come on. I pressed all the buttons, aircon, fan, rear heated window and nothing! Checked the relevant fuses and all ok. Tried again this morning and nothing, on my way home i thought i'd try it and hey presto it came on!!?? Have decided to keep the fan on and not turn it off,
Any ideas as to why this happened anyone?
