I have a problem with my 2006 X5 E53 . it is it seems to be a electronic , the wipers front and back started to act funny working and then just stop for no reason at all now if the wipers don't work the car wont start at all the dash lights comes on but no crank the brake lights stays on and the controls on the steering will only work intermittently. what i do is i leave the car for a few hours and then when switch it on and the wipers work the car will start. And it is getting worse more intermittently. Do anyone know what the problem could be.
