I have a simmilar issue, the radio is going off on a timer of about 30 minutes, and the cigarette lighter plug has stopped working.
I have checked the fuse, and the one for the radio is blown, 15amp, so replaced that, with a spare 15amp, and the cigarette lighter plug is still not working, not had the car switched on long enough yet to see if the timer works on the radio etc.
Any ideas?
I am looking at a Kangoo van 2002 1.2 and to get at the back of the lighter it looks like the whole of the dash has to come forward, it is all one moulding!
