Hey all I am having issues with my 03 A4 cabriolet 3.0. The coolant overflow bottle is spewing out coolant when the engine gets hot. I replaced the cap today but I checked to see if the electric fans were on after I drove the car home from work today and they werent on. They do come on though when I turn on the AC so I know they work. Is there anything that could cause the fans to not work during normal operation?
